5      ==============================      ==============================
6    
7  o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more  o model:
8      - add new 2-d forcing field for time-dependent geopotential anomaly (e.g.,
9        tidal forcing), in m^2/s^2 ; add run-time param to allow to turn it off.
10    o eesupp/src:
11      - shift standardMessageUnit in eeboot.F and I/O units in mdsfindunit.F
12        for coupling to GEOS AGCM: HACK_FOR_GMAO_CPL option in CPP_EEOPTIONS.h
13    
14    checkpoint66k (2017/09/20)
15    o model/src:
16      - add missing CPP brackets (ALLOW_COST, ALLOW_CTRL in load_fields_driver.F
17        and the_model_main.F)
18    o ctrl:
19      - use zeroRL in place of fc when ALLOW_COST is not compiled (in ctrl_pack.F)
20      - call MDS_READ_FIELD / MDS_WRITE_FIELD instead of deprecated
21        mdsreadfield / mdswritefield (in ctrl_get_gen.F, ctrl_map_ini_gen.F,
22        ctrl_map_ini_genarr.F, and ctrl_map_ini_gentim2d.F )
23    o eesupp:
24      - add CPP option to activate some pieces of code for coupling to GEOS AGCM;
25      - shift commonly used IO unit (in eeboot.F) for coupling to GEOS AGCM.
26    o pkg/bling:
27      - bling_production: Fix typo in calcium carbonate uptake. Also rearranging
28        and cleaning
29    o model/src:
30      - move k loop inside correction_step.F (+ update calling S/R)
31      - collect implicit pressure gradient tendencies in local 2-D array;
32        affect results (at machine truncation level) when using 3-D solver; update
33        output of exp.: exp4 (x1), global_ocean.cs32x15 (x2),hs94.cs-32x32x5.impIGW,
34                        rotating_tank, short_surf_wave,tutorial_deep_convection (x2)
35                        & tutorial_plume_on_slope.
36    
37    checkpoint66j (2017/08/15)
38    o pkg/ptracers:
39      - fix surface forcing under ice-shelf (useShelfIce=T).
40    o pkg/atm_phys:
41      - use hFac weighted average when applying A-grid atm-phys momentum tendency
42        to C-grid dynamics; this ensures wind-stress match mom tendency.
43    o eesupp/src:
44      - change default for opening scratch files to avoid STATUS='SCRATCH'
45      - close scratch files with STATUS='DELETE'
46      - changes affect eeset_parms.F and open_copy_data_file.F and many routines
47        that read namelists (because they close the scratch files)
48      - you can revert to old default by setting USE_FORTRAN_SCRATCH_FILES
49        in CPP_EEOPTIONS.h (tested in ideal_2D_oce/code & lab_sea/code_ad)
50    o pkg/atm_phys:
51      - fix unset arguments in (unused) S/R surface_flux_0d.
52    o eesupp/src:
53      - add argument "procId" to S/R EESET_PARMS to fix  scratchFile1 & 2 setting
54        (case TARGET_BGL or TARGET_CRAYXT) for early call (from eeboot_minimal.F):
55        called with myProcId in eeboot.F and with mpiMyWId in eeboot_minimal.F
56    o pkg/streamice:
57      - remove blank between _EXCH_XY_RL and "()", which my Apple Xcode
58        preprocessor /usr/bin/cpp cannot interpret; 3 instances in total in
59        streamice_driving_stress_fd.F and streamice_advect_2dtracer.F
60    o pkg/diagnostics:
61      - new option to allow to cumulate thickness-factor (hFac) weighted field
62        (if field permitted); implemented by changing sign of "jdiag" pointer
63        (> 0: cumlulate field, < 0: cumulate hFac weighted field).
64        a) restricted to 3-d (Nr levels), level centered diagnostics at U,V or Cell
65           center position (gcode(2)='U','V','M' & gcode(3,5,9:10)='R',' ','MR')
66        b) for now, activated by setting fileFlags 3rd character to 'h'.
67    
68    checkpoint66i (2017/07/18)
69    o pkg/cheapaml:
70      - add parameter "useRelativeWind", default set to False; this change the
71        previous setting which was always using relative wind.
72    o add hooks for the Parallel Data Assimilation Framework PDAF
73        (http://pdaf.awi.de/) in eeboot_minimal.F and the_main_loop.F;
74        to use set CPP-flag USE_PDAF in CPP_EEOPTIONS.h
75    o pkg/exf:
76      - interpolation of vector fields (exf_interp_uv.F): fix bug in calculation
77        of South-Pole mean value.  
78      - interpolation near the poles, case where second additional row is at the
79        pole (or beyond the pole and moved to the pole): change first addition row
80        value to a linear interpolation between pole and 1rst (S.pole)/last (N.pole)
81        row (instead of just a copy of it).
82    o pkg/seaice:
83      - prevent JFNK and KRYLOV solvers from trying to reduce a residual of 0
84      - add the option to compute no-slip du/dy, dv/dx (i.e.
85        the offdiagonal strain rate e12) by a second order approximation
86        on the boundary; works only with JFNK, KRYLOV, or EVP solvers, because
87        it is too messy to implement for the implicit LSR matrix.
88        SEAICE_2ndOrderBC = .FALSE. by default
89    
90    checkpoint66h (2017/06/02)
91    o pkg/seaice:
92      - add new routines to compute stress tensor components and stress tensor
93        divergence to be reused in s/r seaice_lsr and s/r seaice_calc_lhs
94      - change names of diagnostics SIsigI/II (commonly used for invariants)
95        to SIsig1/sig2 (more common for principal components) to avoid confusion
96    o pkf/exf:
97      - add a stop if useRelativeWind with un-updated uwind/vwind (e.g., constant);
98        similarly, stop if rotateStressOnAgrid with constant wind-stress.
99    o pkg/seaice:
100      - remove (comment out) diagnostics SIuwind,SIvwind,SIfu,SIfv (duplicate of
101        EXFuwind,EXFvwind,oceTAUX,oceTAUY) and point them to their equivalent.
102      - add diagnostics of wind-stress over seaice (SItaux,SItauy) and seaice
103        fraction weighted wind stress over ocean+seaice (SIatmTx,SIatmTy).
104    o pkg/diagnostics:
105      - small piece of code to rename (old) diagnostics, when namelist is processed.
106    o model/src:
107      - new run-time param (useMin4hFacEdges) to select method for setting hFacW,S:
108        originally, set as minimum of adjacent hFacC factor ; now (new default)
109        computed from rSurfW,S and rLowW,S by applying same rules as for hFacC.
110        Only matters when useShelfIce=T with particular ice-shelf cavity geometry.
111    o pkg/seaice:
112      - add momemtum advection, off by default, still in test phase
113        most of the momentum advection code is adapted and reused from mom_vecinv
114    o pkg/mom_vecinv:
115      - pass these runtime flags:
116        selectVortScheme, highOrderVorticity, upwindVorticity, useJamartMomAdv
117        as formal parameters to s/r mom_vi_u/v_coriolis, mom_vi_u/v_coriolis_c4,
118        so that these routines can also be used in pkg/seaice.
119    
120    checkpoint66g (2017/04/24)
121    o model/src:
122      - more robust ordering of column thickness integral (=Sum_k(drF*hFac) )
123        to get same expression (regarding machine truncation) in different places
124        in ini_masks_etc.F (e.g., rSurfC,W,S is now exactly zero when it should).
125        Update forward output of experiments: global_ocean.cs32x15 (all 5 except
126        viscA4), isomip (x3), tutorial_global_oce_in_p & tutorial_plume_on_slope.
127    o pkg/shelfice:
128      - ALLOW_SHIFWFLX_CONTROL: move setting of maskSHI from shelfice_update_masks.F
129        to shelfice_init_fixed.F
130      - change S/R SHELFICE_UPDATE_MASKS to SHELFICE_INIT_DEPTHS (still called from
131        ini_masks_etc.F for now) to update ocean upper boundary position according
132        to ice-shelf topography (instead of directly updating hFacC).
133    o model/src:
134      - move call to CTRL_INIT & CTRL_ADMTLM from the middle to the bottom of
135        packages_init_fixed.F to allow other pkgs to set mask and weight fields.
136    
137    checkpoint66f (2017/04/06)
138    o model/src:
139      - add specific run-time param to select level of printed plot-field-maps,
140        set by default to debugLevel. Remove internal param "printDomain".
141    o pkg/seaice:
142      - add flag to add snow mass to seaiceMassC/U/V, the default is
143        SEAICEaddSnowMass=.FALSE., not to change previous results
144    o pkg/bling
145      - Bug fix in bling_production regarding unit conversion for diagnostics
146        being put in the wrong place
147    o model/src:
148      - add back recomputation of rSurfW & S to ensure consistent column thickness
149        (needed for rStar) between Sum_k(hFac*drF) and rSurf-rLow, for now only
150        when using pkg/shelfice; was initially added on 2012/06/01 (ini_masks_etc.F
151        revision 1.51) but was removed accidentally on 2014/02/08 (v1.53).
152    o pkg/autodiff:
153      - clean-up "checkpoint.flow"
154    o pkg/rw (Contribution from Jody Klymak):
155        option to set mds file suffix as function of time in simulation:
156        *) new input parameter "rwSuffixType" (read from PARM03 namelist)
157           to select file suffix format; by default (=0), use iteration number;
158        *) add simple routine to return file suffix according to rwSuffixType;
159        *) in model/src and in most pkgs (except: atm2d, fizhi, regrid & streamice),
160           use new S/R to get file suffix, except for debug output file (diagFreq)
161           and pkgs offline & rbcs input files.
162    o pkg/rw:
163      - uniform processing of "I10" suffix across writing fld routines; used to
164        simplify debug writing of cg2/3d_b/x in solve_for_pressure.F & post_cg3d.F
165        (similar to cg3d.F, cg3d_ex0.F)
166    o pkg/mom_vecinv:
167      - highOrderVorticity in selectVortScheme=2 case: fix c4 coeff in splitted
168        vorticity flux (keep same sum in case vBarXm=vBaXp, uBarYm=uBarYp).
169    o pkg/bling:
170      - Many small changes intended to clean the code.
171        Unnecessary ADJOINT_SAFEs removed ;
172        removed BLING_COST.h BLING_CTRL.h bling_cost.F ;
173        diagnostics added.
174    
175    checkpoint66e (2017/03/14)
176    o pkg/exf:
177      - interpolation with #undef EXF_INTERP_USE_DYNALLOC: move buffer size
178        definition outside EXF_PARAM.h in new header file: EXF_INTERP_SIZE.h;
179        use fixed size buffer (passed to S/R EXF_INTERP & EXF_INTERP_UV) to
180        avoid any dynamic allocation ;
181      - S/R EXF_CHECK: add new check & stop when file-name is defined but not
182        read-in ; add warning when file is read-in but not used within pkg/exf ;
183        + check for buffer-size (if #undef EXF_INTERP_USE_DYNALLOC).
184      - update exf_summary.F (print {FLD}RepCycle).
185    o verification/global_with_exf:
186      - switch on exf interpolation in AD test (just like the forward test)
187    o pkg/mom_vecinv:
188      - add storage directives to avoid recomputations within mom_vecinv.F
189        which were generating seg. fault with gfortran -devel
190    o pkg/ctrl, pkg/smooth:
191      - initialize array halos which were generating seg. fault with
192        gfortran -devel in adjoint mode
193    o pkg/exf:
194      - for each input field, enable to specify a field specific repeat-cycle
195        ({FLD}RepCycle) which defaults to pkg/exf main "repeatPeriod".
196    o verification/lab_sea:
197      - update AD results of primary test and noseaicedyn test after switching
198        to new version of TAF (5.3.13 vs 5.3.2 before); agreement with gradient
199        check stays about the same.
200    o pkg/exf:
201      - fix bug in exf_zenithangle.F for cases select_ZenAlbedo > 0 with useCAL=T.
202      - exf_check: MAX_LAT_INC need only be "loc_nlat-1", not equal to loc_nlat
203    o pkg/bling, USE_EXFCO2 code:
204      - add parameter "apco2RepCycle" (set to pkg/exf "repeatPeriod" by default);
205      - update calls to EXF S/R (use new version: EXF_INIT_FLD & EXF_SET_FLD).
206    o pkg/exf:
207      - rename S/R EXF_INIT to EXF_INIT_VARIA ;
208      - add arguments: fldName (for debug msg) and fldRepeatCycle (set to
209        repeatPeriod) to S/R EXF_SET_UV and to S/R EXF_SET_GEN (renamed EXF_SET_FLD)
210        and update calls in pkg/exf calling S/R (exf_getffields.F & exf_getclim.F) ;
211      - add argument: fldName (for debug msg) to S/R EXF_INIT_GEN (renamed
212        EXF_INIT_FLD) and update calls in exf_init_varia.F
213      - For now, for backward compatibility, keep a simplified version of S/Rs
214        EXF_SET_GEN & EXF_INIT_GEN in file exf_set_gen.F
215      - add and pass new arguments: fldName (for debug msg) and fldRepeatCycle
216        to S/R EXF_GetFFieldRec ; update calls in pkg/obcs/obcs_exf_load.F
217    o tools/genmake2:
218      - replace "bc -l" (only used once) by "expr" (already used).
219    o verification/global_ocean.cs32x15:
220      - turn off pkg/cal (useCAL=F) in secondary FWD exp. "icedyn".
221        Note: exf setting (data.exf) can be compared to other exf secondary exp
222        "seaice" (kept with useCAL=T) which has same time dependent forcing.
223    
224    checkpoint66d (2017/02/13)
225    o pkg/exf:
226      - remove setting of useCAL=T when using pkg/exf (useEXF=T); add warning
227        early on (in packages_boot.F) to stress this change in pkg setting.
228      - In (most) verification exp. that use pkg/exf, add useCAL=.TRUE. to data.pkg
229    o model/src:
230      - move call to ecco_phys to end of time step; this may induce minor
231        cost function changes by shifting time averages by one time step
232        for some variables; this revision resulted in changed adjoint results
233        in MITgcm_contrib/verification_other/global_oce_cs32
234    o pkg/exf:
235      - Change EXF_READ_EVAP to only activate code within #ifdef ALLOW_ATM_TEMP ;
236        this prevents to read evap when ALLOW_ATM_TEMP is undef and other fields,
237        e.g. precip, are not available.
238    o pkg/flt:
239      - flt_init_varia.F: use pickupSuff if specified
240      - add code (within #ifdef DEVEL_FLT_EXCH2) and test case as a first,
241        intermediate, step towards completing pkg/exch2 support within pkg/flt;
242        ifdef DEVEL_FLT_EXCH2 then:
243        - flt_init_fixed.F: comment out stop
244        - flt_exch2.F: conserve ipart, jpart (grid coordinates)
245        - exch2_recv_get_vec.F: transform ipart, jpart (grid coordinates)
246        - flt_mapping.F: attempt to fix longitude diagnostic near date-line
247        - flt_init_varia.F: hack initialization (for testing purposes w. LLC90)
248    o tools/genmake2 & pkg/pkg_depend:
249      - define new type of pkg dependency rule ("=pkg_x"), less strict than
250        the "+" rule, that add the dependent pkg (pkg_x) unless it's disabled
251        (-pkg_x in packages.conf).
252      - change pkg/exf dependency rule from "exf +cal" to "exf =cal";
253      - add "+cal" to dependency list of pkg/ecco (needed to compile).
254      - simplify FWD experiment "offline_exf_seaice" by removing pkg/cal.
255    o utils/matlab:
256      - adding ocean_basin routines for defining basin masks.
257    o pkg/exf:
258      - new S/R EXF_GETFFIELD_START replacing EXF_GETFIELD_START, but with more
259        arguments, allowing to check (and stop) if parameter setting of
260         {FLD}startdate1 & date2 and of {FLD}StartTime are consistent with
261        useCAL= T or F. For now, kept a simplified version of EXF_GETFIELD_START
262        for backward compatibility.
263      - change accordingly calls in exf_init_fixed.F + default {FLD}StartTime in
264        exf_readparms.F ; apply same changes to pkg/icefront (for SGRunOff field).
265    o pkg/bling (USE_EXFCO2 code):
266      - fix missing setting of apco2StartTime according to apco2startdate1 & date2
267        by adding a call to S/R EXF_GETFFIELD_START.
268    o pkg/exf:
269      - allows to compile without pkg/cal (but disabled by current dependency
270        rules, i.e., default "pkg/pkg_depend"). Minimal changes to enable to
271        run with useCAL=F ; this involves setting directly {FLD}StartTime instead
272        of {FLD}startdate1 & date2 ; consistency check not yet coded.
273    o verification/global_ocean.cs32x15:
274      - fix all data.exf for a shift of 1 day in all field startdate1 so that it now
275        corresponds to middle of 1rst month; update outputs (2 fwd + 3 adm + 3 tlm).
276    o pkg/exf:
277      - allow to use EXF_ZENITHANGLE without pkg/cal + simplify (saving some
278        calculations); change FWD experiment global_ocean.cs32x15
279        (#define ALLOW_ZENITHANGLE) to test/check that this code compiles.
280    o pkg/exf:
281      - In preparation for addition to NAMELIST, rename internal (_RL) parameter
282         {FIELD}startdate to {FIELD}StartTime
283        Note: new name also fit better the content, i.e, a start time in second.
284    o eesupp/src:
285      - add 1 argument to S/R EEBOOT & EEBOOT_MINIMAL for interface with ESMF
286    o pkg/exf:
287      - add option ALLOW_READ_TURBFLUXES (and corresponding set of parameters)
288        to allow to read-in Sensible & Latent Heat flux ;
289      - simplify pkg/exf main options:
290        1) move small piece of code (case ALLOW_ATM_TEMP undef) out of
291           exf_bulkformulae.F into exf_wind.F so that exf_bulkformulae.F is
292           compiled only when both ALLOW_ATM_TEMP & ALLOW_BULKFORMULAE are defined;
293        2) make call to EXF_RADIATION and to EXF_WIND independent of CPP option
294           ALLOW_BULKFORMULAE which now only applies to S/R EXF_BULKFORMULAE ;
295        3) improve options documentation in EXF_OPTIONS.h.
296    o pkg/ecco:
297      - cost_gencost_customize.F,ecco.h,ecco_phys.F,ecco_readparms.F, and
298        ecco_summary.F: add passive tracer cost functions to gencost;
299        m_ptracer and m_boxmean_ptracer
300    o pkg/ctrl:
301      - ctrl_map_forcing.F: pass myIter and myTime to ctrl_map_forcing as input
302        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing; add to list
303        of implemented gentim2d contol parameters: xx_qnet, xx_empmr, xx_qsw,
304        xx_sst, xx_sss, xx_pload, xx_saltflux, xx_fu, xx_fv, xx_fe, xx_fn
305    o model/src:
306      - forward_step.F: pass myIter and myTime to ctrl_map_forcing as input
307        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing
308    o pkg/exf:
309      - exf_getffields.F: add to list of implemented gentim2d contol parameters:
310        xx_lwflux, xx_swflux, xx_evap, xx_apressure, xx_areamask
311    
312    checkpoint66c (2017/01/19)
313    o verification:
314      - add new option "-src" to testreport to only produce source code (*.f),
315        including taf output src code (if using '-adm'/'-tlm' option).
316    o pkg/exf:
317      - add saltflx :: Net upward salt flux in psu.kg/m^2/s
318    o pkg/diagnostics:
319      - add run-time variable diagMdsDir to specify a subdirectory for
320        diagnostic output when mds is being used and mdsioLocalDir is not.
321    o pkg/mnc:
322      - mnc_utils.F: edit stop message
323    o pkg/autodiff:
324      - autodiff_ini_model_io.F: PRINT_MESSAGE, clean-up comments, add _*_MASTER,
325        add HAVE_SYSTEM bracket around system call to mkdir
326    o pkg/profiles:
327      - profiles_findunit.F, profiles_init_fixed.F, profiles_interp.F,
328        profiles_readparms.F: call ALL_PROC_DIE before 'stop'
329      - profiles_ini_io.F: use PRINT_MESSAGE, clean-up comments, add _*_MASTER,
330        add HAVE_SYSTEM bracket around system call to mkdir
331    o pkg/smooth:
332      - smooth_filtervar2d.F, smooth_filtervar3d.F: call ALL_PROC_DIE before 'stop'
333      - smooth_init2d.F, smooth_init3d.F: move print statements to readparms
334      - smooth_readparms.F: add cleaner print statements from smooth_init?d.F
335    o pkg/exf:
336      - check: count errors and stop cleanly at the end (call to ALL_PROC_DIE);
337        issue error message when climsst_interpMethod.GT.0 and climsst_lon_inc > 500
338        generalize tests on interpMethod, nlat, and lon_inc to all exf variables.
339      - summary: skip detailed field report if not used (empty file-name).
340    o tools/xmakedepend:
341      - In case line editor "ed" is missing, switch to "sed" command to clean-up
342        Makefile from previous dependencies (anything after "# DO NOT DELETE" line).
343    o pkg/exf:
344      - change definition of "hflux" input file to always include Short-Wave;
345        this is now consistent with hflux computation (if using bulk-formulae)
346        and hflux diagnostic & documentation (in EXF_FIELDS.h).
347    
348    checkpoint66b (2016/12/01)
349    o model & momentum pkgs:
350      - implement fully implicit bottom friction combined with implicit surf.
351        pressure, for now, only in hydrostic formulation:
352        + to use: compile with #define ALLOW_SOLVE4_PS_AND_DRAG in CPP_OPTIONS.h
353          and run with selectImplicitDrag=2 ;
354        + currently missing diagnostics of bottom drag and vert. viscosity tendency;
355      - partial implicit time-stepping (bot. friction + vert. visc first, then
356        surf. press) corresponding to selectImplicitDrag=1 should be applicable
357        to NH formulation but not available until we solve for surf. pressure
358        increment (instead of full etaN).
359      - change exp. global_ocean.cs32x15.thsice to test implicit bottom drag
360        with implicit vertical viscosity.
361    o pkg/seaice: add linear remapping scheme (Lipscomb 2001) to ITD model
362      - this is a first version that includes many regularisations that may
363        not all be necessary, to be sorted out,
364      - turned on by runtime parameter SEAICEuseLinRemapITD (true by default)
365      - change one verification experiment in seaice_itd to use and test new code
366      - seaice_growth: catch a case where the argument of log can be zero
367        or smaller (important for code stability)
368    o model/src:
369      - modify SOLVE_DIAGONAL_LOWMEMORY version of solve_tridiagonal.F
370        & solve_pentadiagonal.F to enable to re-used inverse matrix for solving
371        similar A.X'=Y' system (with same matrix A) in subsequent calls;
372        switch based on errCode (In/Out) argument value; in calling routines,
373        initialise errCode before first call.
374    
375    checkpoint66a (2016/10/18)
376    o pkg/bling:
377      - BLING package now loads in atmospheric pCO2 file using exf package routines
378        Enable with #define USE_EXFCO2 in BLING_OPTIONS.h
379    o model/src & pkg/ptracers:
380      - with INCLUDE_IMPLVERTADV_CODE defined, also call MOM_U,V_IMPLICIT_R &
381        GAD_IMPLICIT_R (instead of IMPLDIFF) when just implicitViscosity and
382        implicitDiffusion (respectively) are used (even without momImplVertAdv
383        or temp,salt,PTRACERS_ImplVertAdv).
384    o model/src & generic_advdiff:
385      - add parenthesis in main diagonal calculation of implicit vertical
386        diffusion matrix (impldiff.F & gad_implicit_r.F).
387        This affects results at machine truncation level; update output of many
388        verification experiments (31 fwd ; 10 adm ; 8 tlm ; 3 oad).
389    o pkg/mom_commom & generic_advdiff:
390      - add deep atmosphere and anelastic scaling factor in implicit vertical
391        advection routines (mom_u,v_implicit_r.F & gad*_impl*_r.F).
392    o model/src:
393      - remove few unnecessary temp array copies in solve_tridiagonal.F
394        & solve_pentadiagonal.F
395    
396    checkpoint65z (2016/09/28)
397    o pkg/seaice: fix multithreading for seaice_fgmres.F
398      - remove unecessary variables from common blocks
399      - use extra dimension MAX_NO_THREADS for all variables of the Krylov space
400        basis, that are stored in commom blocks (including integer variable i1)
401      - clean up code a little by removing commented lines that refer to
402        original code
403      - turn on multi-threaded test for experiment offline_exf_seaice.dyn_jfnk.
404    o MITgcm manual:
405      - add uptodate pkg/ecco documentation to the manual (section 8.1; ecco.tex),
406        preliminary documentation for generic controls (8.3; ctrl.tex),
407        a placeholder for smooth (8.4; smooth.tex), and comment out the deprecated
408        ecco_costfunction.tex
409    o pkg/ecco:
410      - update and cleanup list of CCP options
411      - re-assign gencost_mask to specify masks rather than gencost_errfile; 'c'
412        is now always passed to cost_generic; gencost_mask is now MAX_LEN_FNAM
413      - add checks that retired run-time options are not used, and in relation
414        to gencost_mask and gencost_errfile
415      - finish deprecating gencost_scalefile, gencost_smooth2Ddiffnbt, and
416        gencost_nrecperiod
417      - fix m_eta computation for virtual salt flux case
418      - add m_horflux_vol case (selected via gencost_barfile) that computes
419        transports via cost_gencost_boxmean (gencost_flag=-3)
420      - use gencost_flag more systematically (i.e., avoid using gencost_name)
421        for code switches (aside from physical variable selection)
422    o pkg/seaice: make seaice_fgmres.F fit for multithreading; this first
423      attempt appears to be a bit of a hack and my need some repair down the road
424    o pkg/exf:
425      - interpolation near South Pole: fix criteria on input field latitude.
426    o pkg/icefront & pkg/exf:
427      - move setting of icefront Sub-Glacial RunOff forcing (currently unused)
428        from pkg/exf (read from data.exf) to pkg/icefront (read from data.icefront)
429    o pkg/exf:
430      - replace CPP option ALLOW_EXF_OUTPUT_INTERP with run-time parameter
431        "exf_output_interp" (in namelist: EXF_NML_04); change output file name
432        (add suffix "_out" instead of a prefix); keep same record number as in
433        input file but always write record 1 first (to avoid a STOP in I/O S/R).
434        Change output file content by writing interpolated field before applying
435        land-sea mask (helpful for debug).
436      - 2 compon. vector interpolation with rotation: apply scaling factor on
437        each compon. (Eastward and Northward) just before rotation.
438    o pkg/bling:
439      - Cleaned package. Removed not needed code and comments.
440      - adjoint example now works
441        (MITgcm_contrib/verification_other/global_oce_biogeo_bling/code_ad)
442    o pkg/ptracers:
443      - add Bruno Deremble's code to complete the linear surface correction
444        for tracer conservation;
445      - enabled for individual ptracers by PTRACERS_linFSConserve(iTr)=.TRUE.
446    
447    checkpoint65y (2016/07/29)
448    o pkg/debug (stats):
449      - change GLOBAL_SUM to GLOBAL_SUM_TILE (result independent of tile to
450        proc/thread mapping);
451      - fix Min & Max for case where 1 thread has only empty tiles;
452      - use RL variable to count number of wet grid points (with big domain,
453        can be too large to fit into integer*4).
454    o pkg/monitor:
455      - use RL variable to count number of wet grid points (but used only for del2)
456      - add new routine to compute Advective CFL within tracer time-stepping with
457        writing delayed until next monitor output.
458    o pkg/obcs:
459      - fix bug in OBCS_BALANCE_FLOW (OBCS_balanceFacN misspelled OBCS_balanceFacW)
460    o pkg/cal:
461      - calandar-dump: treat case myTime < timePhase in the same way as in
462        eesupp/src/diff_phase_multiple.F (when not using calandar-dump).
463    o pkg/dic & seaice:
464      - fix compilation of ocean component for coupled atm+ocn model with
465        seaice dynamics & dic.
466    
467    checkpoint65x (2016/06/11)
468    o add a license text file in main MITgcm tree.
469    o added pkg/bling:
470      - intermediate complexity biogeochemical model
471      - see bling_description.txt for details
472      - verification experiment is global_oce_biogeo_bling (for now, in
473        Contrib/verification_other/); tested daily on baudelaire with gfortran.
474      - add entry point in pkg/gchem for new pkg "bling".
475    o pkg/seaice: fix tensile stength computation
476      - replace global field tensileStrength by tensileStrFac
477      - tensileStrFac can be computed once in S/R seaice_init_varia
478      - fortunately that does not affect any verification results
479    
480    checkpoint65w (2016/05/12)
481    o pkg/ctrl/ctrl.h: fix a comma in common block list, so that code compiles
482         with ECCO_CTRL_DEPRECATED defined
483    o verification/global_ocean.cs32x15:
484      - change secondary test "viscA4" to also test "selectP_inEOS_Zc=3"
485        with "selectNHfreeSurf=1".
486    o model/src (non-hydrostatic free-surface):
487      - More "natural" expression of NH free-surface term (case selectNHfreeSurf=1):
488        was: tmpSurf/(1+tmpSurf); changed to: 1/(1+Gamma) with Gamma=1/tmpSurf.
489      - Calculate surface vertical velocity after 2-D solver adjustment (accounts
490        for EmPmR if RealFreshWaterFlux); used in RHS (cg3d_b) if exactConserv
491        and used to compute dPhiNH (in post_cg3d.F) if selectNHfreeSurf=1.
492        This fixes EmPmR contribution when selectNHfreeSurf=1 & RealFreshWaterFlux.
493      - Update output (changes at machine truncation level) of verification exp:
494        exp4 (11 digits for cg2d), global_ocean.cs32x15.viscA4 (11.d),
495        short_surf_wave (13.d) and tutorial_deep_convection.smag3d (12.d).
496    o pkg/seaice: ITD code
497      - fix picking up from a single category model by initialising
498        heff/area/hsnowITD = 0. in seaice_itd_pickup.F
499      - split a long warning message in seaice_check_pickup.F into two lines,
500        because NEC SX-ACE cannot deal with the long line.
501    o model/src:
502      - fix missing dPhiNH in pressure_for_eos.F (case: selectP_inEOS_Zc=3)
503    o pkg/seaice:
504      - add missing checks for SEAICE_ALLOW_KRYLOV and SEAICE_ALLOW_BOTTOMDRAG
505    o pkg/seaice:
506      - add basal stress as parameterisation for grounding ice
507        following Lemieux et al. (2015)
508      - turn on by setting new parameter SEAICEbasalDragK2 to a value
509        larger than 0. Lemieux et al. (2015) recommend 15.
510      - The adjoint complains with extra recomputations so there is also a
511        new cpp-flag SEAICE_ALLOW_BOTTOMDRAG that is undefined by default in
512        order to postpone the problem
513      - compile the new code in lab_sea
514    o verification/halfpipe_streamice:
515      - update both TAF and OpenAD adm output (machine truncation differences)
516    
517    checkpoint65v (2016/04/08)
518    o verification/advect_xz:
519      - increase overlap size from 3 to 4 and add new secondary test for PQM
520        advection scheme (with mono & wino limiter).
521      - change main exp. to test PPM (with weno limiter) adv.scheme on Temp.
522    o model/src:
523      - new parameters "top_Pres" & "seaLev_Z" (replacing Ro_SeaLevel and recently
524        added phi0Ref) to set vertical axis origin and phiRef origin;
525        keep Ro_SeaLevel for backward compatibility (with a warning).
526       According to coordinate and fluid type:
527        OCN in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(1), @ the top)
528        ATM in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(Nr+1) @ bottom)
529        OCN in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(Nr+1)/g, @ the top)
530        ATM in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(1)/g, @ the bottom)
531      - remove Ro_SeaLevel from ATM experiment parameter files;
532      - in tutorial_global_oce_in_p, remove Ro_SeaLevel and set top_Pres to the
533        complement; update output.txt (changes at machine truncation level).
534    o pkg/seaice/seaice_evp.F
535      - simplify computation of deltaZ and zetaZ to simple averaging following
536        Bouillon et al. (2013). This removes a lot of code, but also changes
537        verification experiment lab_sea.hb87 -> updated
538    
539    checkpoint65u (2016/03/14)
540    o pkg/generic_advdiff:
541      - from Darren: add PPM and PQM advection schemes (number 40-42 and 50-52)
542        with 2 types of limiter (see: Engwirda & Kelley, submit. to JCP);
543        Note (from Darren): unlimited PPM/PQM scheme (40 & 50) are just for
544        testing and not for actual use.
545    o model/src:
546      - add parameter "phi0Ref" to specify reference [pressure/geo] potential at
547        origin r = rF(1);
548      - add options (parameter selectP_inEOS_Zc) to select which pressure to use
549        in EOS for height coordinate: enable to include NH Pressure or to use
550        more accurate pressure vertical profile; options not linked to EOS type
551        (as previously, e.g., JMD95P/JMD95Z) but set default according to EOS type;
552      - start to implement variable gravity (along vertical): for now, only with
553        z-coords (not even z*).
554      - add Ideal Gas equation of state for height coordinate.
555      - update OpenAD output (affected at machine truncation level) of exp:
556        global_ocean.90x40x15, OpenAD (std) and tutorial_global_oce_biogeo.
557    o pkg/exf:
558      - add ALLOW_EXF_OUTPUT_INTERP cpp switch to output the result
559        of exf interpolation (before any rescaling, rotation or interpolation
560        to velocity point) for each field that gets loaded from file. This option
561        identically mimics the input file organization (e.g. record numbers in year
562        by year input files) besides the change in horizontal grid.
563      - add rotateStressOnAgrid run-time switch so that wind stress fields
564        can be provided on the A-grid in zonal/meridional direction and
565        rotated on the fly. This only applies to the case when the exf
566        interpolation is off and rotateStressOnAgrid is false by default.
567    o model/src:
568      - rename internal parameter "useDynP_inEos_Zc" to "storePhiHyd4Phys" (since
569        it's also used with pkg/atm_phys) and add few more parameters (but still
570        inactive, src code yet to come)
571    
572    checkpoint65t (2016/02/10)
573    o pkg/atm_phys:
574      - from Ruth Geen: add optical depth dependence on CO2 concentration.
575    o model/src:
576      - fix vertical inter/extra-polation of density factor rhoFacF (for anelastic)
577        for the case setCenterDr=T (delRc set from "data"); add output of rhoFacC&F.
578        Update output of exp. deep_anelastic (changes at truncation level).
579    o tools:
580      - add a hack in "remove_comments_sed" (used only with TAF) for recent
581        version of OpenMPI (shipped with FC.23): comment out the new header
582        file "mpif-sizeof.h" which causes problems to TAF.
583    o pkg/seaice:
584      - change the termination criterion so that maxits (SEAICElinearIterMax)
585        has an effect
586      - unify iteration parameters for implicit solvers (JFNK and Picard)
587        SEAICEnonLinIterMax replaces SEAICEnewtonIterMax/NPSEUDOTIMESTEPS
588        SEAICElinearIterMax replaces SEAICEkrylovIterMax/SOLV_MAX_ITER
589        SEAICEpreLinIterMax replaces SOLV_MAX_ITER in preconditioner
590        SEAICEpreNL_IterMax replaces NPSEUDOTIMESTEPS in preconditioner
591        SEAICEnonLinTol     replaces JFNKgamma_nonlin
592      - remove S/R SEAICE_FGMRES_DRIVER and put content into S/R SEAICE_JFKN
593      - add new Picard-Krylov solver, compile with SEAICE_ALLOW_KRYLOV and
594        use with SEAICEuseKrylov
595    o pkg/seaice/seaice_lsr.F
596        fix small bug: replace zetaZ by zetaZloc in S/R seaice_lsr_rhsu/v; only
597        relevant if SEAICEuseStrImpCpl=T, and even then it does not seem to have
598        an effect.
599    o pkg/seaice: add two new parameters
600      - SEAICEuseLSR to simplify the logic in seaice_dynsolver (this
601        parameter is not in any namelist)
602      - SEAICEusrPicardAsPrecon to allow s/r seaice_lsr to be used as
603        a preconditioner for the non-linear Newton iteration of the JFNK
604        solver
605    o pkg/seaice/seaice_lsr.F: replace 1./SEAICE_deltaTdyn with recip_deltaT,
606      affects some experiments at truncation level:
607      - global_ocean.cs32x15.icedyn (11 digits),
608      - global_ocean.cs32x15.seaice (11 digits),
609      - seaice_itd (12 digits), seaice_itd.lipscomb07 (12 digits) -> update
610      - also update global_ocean.cs32x15 adjoint and tangent-linear results
611    o pkg/salt_plume & pkg/thsice:
612      - for coupled  set-up with pkg/thsice in ATM and pkg/salt_plume in OCN,
613        connect salt_plume flux to ATM-OCN coupling pkgs interface:
614       a) in ATM: also cumulate salt-plume flux in S/R THSICE_SALT_PLUME (for
615         export to coupler interface) even without compiling pkg/salt_plume ;
616       b) in OCN: apply coupler salt-plume flux to pkg/salt_plume field
617         (saltPlumeFlux) just before exch call, in S/R SALT_PLUME_DO_EXCH.
618    o pkg/dic:
619      - use the updated seaice fraction (from seaice pkgs) for DIC forcing
620        instead of the previous time-step value ; done in new S/R DIC_FIELDS_UPDATE
621        called from the top of dic_biotic_forcing.F (instead of in DIC_FIELDS_LOAD);
622      - move also update with values from ATM-OCN Coupler in the same new S/R
623        (previously done in ocn_apply_import.F).
624    o tools/adjoint_options:
625      - specify explicitly "-f77" or "-f90" in default ad-optfile since TAF (default)
626        has been changed on Jan 14, 2016.
627    o pkg/ggl90:
628      - add alternative discretisation of vertical shear (off by default), to
629        compute the mean (@ grid-cell center) of vertical shear compon instead of
630        vertical shear of mean flow (@ grid-cell center).
631      - add correct parenthesis in ALLOW_GGL90_SMOOTH code to get the same truncated
632        results on adjacent faces of cubed-sphere grids; this fix the restart.
633    o pkg/atm_compon_interf:
634      - skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just
635        pass last value, stored directly before export to CPL ;
636        Note: this affects results of Coupled set-up where OCN uses useImportSLP=T
637      - remove atmSLPr from pickup files (no longer needed for restart)
638    
639    checkpoint65s (2016/01/13)
640    o eesupp & genmake2:
641       - first check for Function ETIME and, if it fails, then check for subroutine
642         ETIME and consistent output; use the appropriate version in timers.F
643    o model/src:
644      - to check restart test, add option to apply EXCH to U,V earlier, just before
645        integr_continuity; turned off by default.
646    o pkg/dic:
647      - remove CPP option USE_ATMOSCO2 (not needed)
648    o tools/tst_2+2:
649      - try to ignore difference between +0 and -0 in binary file, causing test
650        to fail for no good reason.
651    o eesupp & genmake2:
652      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
653        but also check (in genmake2) that test runs and returns meaningful results.
654    o coupler pkgs:
655      Finish implementation of optionally-exchanged variable switches (started on
656       Nov 12) with addition of few more exchanged fields, including 2-way exchange
657       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
658       advection in OCN component; this requires sequential coupling.
659      coupler (pkg/atm_ocn_coupler):
660      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
661        routines (useful for debug).
662      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
663         flux, DIC fields) if corresponding switch is ON.
664      - add option to export RunOff to OCN (to use for DIC river input)
665      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
666      components (pkg/atm_ & ocn_compon_interf):
667      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
668        optionally exchanged fields; add a check & stop in cpl_readparms.F.
669        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
670        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
671      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
672        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
673      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
674      - hold in common block coupler optionally-exchanged variable switch
675        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
676      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
677        this is intended to replace the OCN cplFldtave.* output files (not updated
678        to contain new additional exchanged fields).
679    o pkg/dic:
680      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
681    o pkg/thsice:
682      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
683        and writing of thsice pickup files.
684    o pkg/atm_compon_interf:
685      - move all field individual export-call out of cpl_export_import_data.F
686        into new S/R ATM_EXPORT_FIELDS
687    o pkg/atm_compon_interf:
688      - store state variables (for now, only thSIce fields) just before beeing
689        exported (in cpl_export_import_data.F, like on ocean side) instead of from
690        atm_store_my_data.F like all exported fluxes.
691      - new version of pickup_cpl: write field names into meta file and read meta
692        file to find field postion in pickup. Also only write/read fields meeded for
693        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
694    o pkg/dic:
695      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
696    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
697        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
698        value can be from domain [0,1] to average between the two methods
699    o pkg/atm_phys:
700      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
701        hold fixed in time).
702    
703    checkpoint65r (2015/12/21)
704    o pkg/seaice:
705        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
706        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
707    o pkg/seaice:
708      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
709        when SEAICEscaleSurfStress=.TRUE.,
710      - apply areaW and areaS in S/R seaice_calc_lhs
711    o pkg/atm_phys:
712      - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
713        (shortwave & longwave, net & downward) and diagnostics of temp. tendency
714        for individual contribution (convection, LSC cond, radiation)
715      - add Ruth Geen etal, GRL 2016, radiation options (see paper supp.
716        information); activated with: solar_exponent=0. and wv_exponent=-1.
717    o pkg/ggl90:
718      - within IDEMIX add upper limit for horizontal group velocity to
719        avoid instability problems in the explicit horizontal diffusion term for
720        long time steps or high resolution
721    o pkg/diagnostics:
722      - simplify setting of local-array size in diagstats_output.F: uses "numLevels"
723        (from DIAGNOSTICS_SIZE.h) to allow to write out more than Nr levels.
724    o testreport:
725      - remove "-v" (verbose option) in default mpirun command.
726    o pkg/seaice/seaice_growth:
727      - catch potential division by zero in ITD code, does not change
728        verification results
729    o pkg/ecco:
730      - retire old codes to the Attic. The calls to retired functions are
731        left in a commented form in case they ever need to be re-activated.
732      - ecco_check.F: issue warning if any old CPP option is
733        defined that corresponds to retired codes -- then stop.
734    o pkg/atm_compon_interf:
735      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
736        coupler: use last time-step value instead of average over cplSendFrq_iter
737        time-step, similar to what is done for seaIceMass.
738        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
739    o eesupp & genmake2:
740      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
741        <= remove until a fix is found for some ifort version on ia32 machine.
742    o pkg/seaice/seaice_evp:
743      - refine residual computation
744    
745    checkpoint65q (2015/11/18)
746    o pkg/seaice/seaice_evp:
747      - fix residual computations so that they no longer affect the actual
748        simulation code
749      - fix seaice_readparams to be able to actually set new parameters
750        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
751    o model/src:
752      - fix wrong truncation (single prec) from "FLOAT" function in expressions
753        like: deltaT*FLOAT(myIter) when myIter is large:
754         a) replaced by DFLOAT (if not seen by TAF);
755         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
756    o pkg/aim_v23:
757      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
758        when pickupSuff is set ; do write rolling pickups + at the end of the run.
759    o pkg/atm_ocn_coupler + ocn_compon_interf:
760      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
761        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
762        add corresponding call in DO_OCEANIC_PHYS.
763    o coupler pkgs:
764      Start a new way to set-up optionally-exchanged variables (previously, only
765       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
766       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
767       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
768       compononent param default can be set accordingly).
769      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
770       but rather applies to a group a fields (going both ways like for DIC)
771       and corresponds to an option of coupling config.
772      coupler (pkg/atm_ocn_coupler):
773      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
774        and read namelist directly (without eessup S/R calls) instead of
775        in the very un-flexible old way, 1 param per line, in fixed order;
776      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
777        cleanly in CPL_CHECK_CPLCONFIG
778      - add new coupling-exchange selectors (some not yet active) including
779        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
780                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
781      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
782        component ; called directly from coupler.F, after comp. registrations;
783      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
784         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
785          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
786      components (pkg/atm_ & ocn_compon_interf):
787      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
788        CPP header file in all pkg source files.
789      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
790        ATM/OCN_CHECK_CPLCONFIG;
791      - add error-counter to track errors (e.g., in "data.cpl") and to stop
792        cleanly in ATM/OCN_CHECK_CPLCONFIG;
793      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
794        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
795        before PACKAGES_READPARMS;
796      verification/cpl_aim+ocn/:
797      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
798        "data.cpl" for coupler (in input_cpl).
799    o eesupp/inc:
800      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
801        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
802        to always cumulate tile local-sum in the same order (still uses
803        MPI_Allreduce like standard code).
804      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
805        that are now identical to standard version (in eesupp/inc).
806    o pkg/shelfice:
807      - add SHELFICETransCoeffTFile for initializing spatially varying
808        heat and salt transfer coefficients
809    o pkg/atm_compon_interf & ocn_compon_interf:
810      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
811        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
812      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
813    o pkg/atm_ocn_coupler:
814      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
815    o pkg/rbcs:
816      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
817        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
818      - add a short report (to STDOUT) about RBCS-mask settings.
819    
820    checkpoint65p (2015/10/23)
821    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
822        there is no adjoint test for EVP, we don't know what it does to the adjoint
823        solution, but at least there are no more recomputation warnings left
824    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
825        a chance of giving the same results as a fully converged VP (JFNK) solver
826    o tools/adjoint_options/adjoint_diva:
827      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
828    o pkg/streamice:
829      - spotted bug in streamice_driving_stress using dyG where should have been dxG
830    o pkg/exf:
831      - remove STOP statement that prevented to use wind or (wind-)stress
832        interpolation for constant-in-time forcing fields (wind/stress period = 0).
833    o pkg/seaice:
834      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
835        5 additionals 2D fields and 6 new store directives
836      - change logic in seaice_readparms.F: EVP code can now be turned on in
837        various ways, setting SEAICE_deltaTev is no longer required,
838        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
839        or SEAICEaEVPcoeff
840    o pkg/shelfice/shelfice_thermodynamics.F
841      - redefining uLoc/vLoc to u/v, instead of 2u/v
842    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
843      - this is an intermediate state of a truely converging EVP that has
844        the potential of outperforming implicit VP methods, I do not recommend
845        using it yet.
846      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
847        and all parameters are hardwired
848      - for convergence it still requires very smooth regularisations, that means,
849        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
850        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
851        specific averaging appears to be required, still subject to tuning
852      - still needs cleaning and I need to turn parameter into runtime parameters
853      - add code to compute and print residuals of iteration, compile with
854        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
855    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
856      that entered with r1.54 on Sep04, 2015, -> update results
857    
858    checkpoint65o (2015/09/14)
859    o pkg/mom_vecinv & mom_common:
860      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
861        called from there.
862      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
863        allows to use Vector-Invariant form in deep atmos and anelastic formulation
864    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
865      and Koenig-Beatty+Holland (2012)
866      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
867      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
868      - requires an extra input argument for S/R seaice_calc_viscosities
869      - tensileStrength's depth dependence is different from Itkin et al. (2015)
870        (to be changed and played with, for now exponential)
871    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
872      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
873        by AREA according to Connelly et al. (2004), JPO.
874      - For EVP and the LSR solver, the implicit part of the drag term is
875        the only non-zero term in the denominator when there is no ice (which
876        prevented running the model with zero ice-ocean drag). If
877        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
878        (or zero main diagonals BU/BV) which need to be caught. A practical
879        consequence is that for open water, the momentum equation reduce
880        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
881        they happen to be zero, often leading to a non-zero solution over
882        open water.
883    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
884      efficient EVP method.      efficient EVP method.
885    - introduce area-weighted averages for e12 (analogously to    - introduce area-weighted averages for e12 (analogously to
