5      ==============================      ==============================
6    
7    o modify exp4 to test new obcs support reading from external files
8      and for passive tracers
9    o fix behavior of ptracers_monitor when monitor output is written to a
10      netcdf-file; still not independent of monitor.F (writes in the same
11      file).
12    o change default value of tRef (put a uniform, meaningful value for ocean
13      & atmos) and initialize sRef (was missing, as Martin mentioned).
14    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
15      to be proportional to enstrophy dissipation length.  Thus,
16       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
17      This is now consistent with Smagorinsky and with the manual.
18    
19    checkpoint57u_post
20    o OBCS and PTRACERS: add open boundary support for passive tracers
21      - either use homogenous (pseudo) v.Neumann conditions or prescribe
22        OB-values from file; this is not different from the way theta and salinity
23        are treated
24      - however, Orlanski-radiation conditions are not supported, and the model
25        will stop if you use pTracers and Orlanski at the same time.
26      - beefed up the rountine obcs_external_fields_load: now only those open
27        boundary values are overwritten with values from files for which there
28        are really files, otherwise the OB-fields remain untouched. This makes
29        it possible to use different OBs at different ends of the domain (as
30        with EXF)
31    o reduce number of exch calls in shap_filt (s2).
32    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
33      truncation level) 4/5 MLAdjust test results (11&12 digits match).
34    
35    checkpoint57t_post
36    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
37    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
38      same truncation, independent of the face number: affects affects several
39      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
40    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
41      note that biharmonic viscosity + no-slip was not tested in any experiment.
42    o fix bug in non-linear free-surf side-drag ; generate new output for
43      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
44    o make mnc honor the writeBinaryPrec flag for most kinds of output
45    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
46    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
47      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
48    o add brackets in multi-terms sum to get same truncation, independent of
49      the face number (manage to get exactly same value of gU,gV at the cs-edge)
50      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
51    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
52      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
53      a maximum grid-scale Reynolds number.  Also, changes all length calculations
54      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
55      Suggested values of viscosity parameters found in mom_calc_visc.
56      Many new viscosity diagnostics available.
57    
58    checkpoint57s_post
59    o Add clearing-house for viscosity calculations, mom_calc_visc and
60      correct numerous bugs in LeithD and Smagorinsky discretizations.  
61      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
62      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
63      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
64      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
65      The Strain-Tension form is now called with useStrainTensonVisc=.true.
66      ViscAhStrain and viscAhTension are now retired.
67    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
68    o In response to JMC's bug report, genmake2 now ignores any soft-links
69      that it finds in the *current* directory when searching for files.
70      Soft-links found in any other source directories will still work as
71      they did before.
72    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
73      a C routine to unlimit the stack size
74    o mnc-ify pkg/aim snapshot vars
75    o mnc-ify pkg/land as requested by Daniel
76    o various changes to mnc including:
77      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
78      - output can now be grouped so that all files within a group
79          change the ITER portion of their names in lock-step together
80      - can now read ("global") PER-FACE (in addition to PER-TILE) files
81          and works with both EXCH1 and EXCH2 (but needs more testing)
82      - writing works for all verification test cases w/ g77 on Linux
83    
84    checkpoint57r_post
85    o make MNC variable initialization happen earlier
86    o add diagnostics for (almost) each term of the momentum Eq.
87    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
88    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
89    o remove MINIMAL_TAVE_OUTPUT option ;
90      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
91    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
92      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
93    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
94    o add time-dependent SST, SSS control
95    o cost terms in ecco/ modularized (new cost_generic.F)
96    o cost_averages routines are modularized (new cost_averagesgeneric.F)
97    o new infrastructure for seaice model vs. obs misfits in seaice/
98      * driver from the_main_loop.F is seaice_cost_driver.F
99      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
100      * gradient check in Exp. 6a of natl_box_adjoint/
101    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
102      (see README file)
103    
104    checkpoint57q_post
105    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
106    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
107      - bug was reported by Jean-Michel and Ian Fenty
108    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
109      update exp. cpl_aim+ocn output.
110    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
111      Needed for high-res. runs with large global files
112      to be able to limit tapelev size
113    o Changed some tests for adjoint:
114      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
115      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
116      * global_ocean.90x40x15/ back to default 3-level checkpointing
117    o Modifications to enable scripted COMMON to MODULE conversion
118      * verification/OpenAD/code/ has necessary scripts and description;
119      * converts, compiles and runs successfully;
120    
121    checkpoint57p_post
122    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
123    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
124      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
125    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
126    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
127      (was already the case for dissipation with mom_vecinv,
128       and also the case for grad.PhiHyd when staggered-timeStep)
129      This will allow to put dissipation out-off the AB time-stepping.
130     Unfortunately, affects truncation error. Update output of exp. that "fails"
131      (cg2d matching number) and leave the others for later: front_relax(10),
132      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
133      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
134    
135    checkpoint57o_post
136    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
137      (2) its ready to be documented during the 20050801 DocFest
138    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
139      for ideal_2D_oce and lab_sea on linux_ia32_g77
140    o set to #undef CTRL_SET_OLD_MAXCVARS_30
141      in global1x1_tot/code_seaice_adj to access indices 32, 33
142      (worth another tag)
143    
144    checkpoint57n_post
145    o adding precip control xx_precip 32
146    o adding swflux control xx_swflux 33
147    o Replacing 10 forcing penalty cost routines by 1 generic.
148    o Implementing partitioning in time-mean and variable adjustment
149      for atmos. state.
150    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
151    o in natl_box_adjoint:
152      * updated exp 1 to 10
153        (but does not have time-mean vs. variable split results yet)
154    o updated global1x1/*_seaice_adj/
155      to incorporate latest changes
156    o enable useSingleCpuIO for mdsio vector routines
157      (applies in particular to tapelev I/O)
158    o removed inefficient K-loop in all active_file*control*.F
159    
160    checkpoint57m_post
161    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
162      and advect_cs (use EXCH-2 and standard cs-32 grid files).
163    o pkg/exch2: filling of face-corner halo regions is optional
164      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
165    
166    checkpoint57l_post
167     tag before updating tutorials (pre-release-2)
168    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
169       for output and interpolation of input fields onto model grid)
170    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
171       Affects results of exp. rotating_tank ; update output.txt.
172    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
173          and taking the square quantity and/or using a fraction-weight field.
174    o fix aim_diagnostics_init.F mate numbers.
175    o add mnc output capability to diagnostics/diagstat and update
176      our cvsignore files for the ACSII output generated
177    
178    checkpoint57k_post
179    o lab_sea now uses diagnostics package and provides a suite of
180      new EXF diagnostics output.
181    
182    checkpoint57j_post
183    o exf
184      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
185        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
186        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
187      * extended diagnostics output
188        - now includes all EXF variables
189        - hs, hl moved to common block
190        - separate S/R for diagnostics, called after ctrl vector is added
191        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
192        - EXFqnet contains true Qnet (i.e. includes qsw)
193      * updated verif. lab_sea, global_with_exf
194      * Rearranging hflux (exf_mapfields -> exf_getforcing)
195        to ensure that diagnostics sees a true EXFqnet
196    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
197    o diagnostics pkg: change pointers so that 1 diagnostic can be used
198      several times with different frequencies.
199    o mnc-ify the thsice package as requested by Daniel Enderton
200      - the monitor--MNC output needs work
201      - many attributes need to be added (most are currently blank)
202    o mnc-ify theaim_v23 package as requested by Daniel Enderton
203      - many attributes need to be added (most are currently blank)
204    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)

206    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
207      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
208         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
209    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
210     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
211    
212    checkpoint57i_post
213    o Diagnostics package was changed: diagnostic allocation is now deactivated
214      by setting an empty file name in the namelist (used to be by setting 0 frequency)
215    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
216      add 1rst Order upwind vertical Shear.
217    o add a quick fix for A/B checkpointing in OFFLINE mode
218    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
219      end-run around the C/Fortran linking horror in eesup/src/timers.F
220    o added pkg/runclock: allows user to terminate run based on wall clock
221    o added non-hydrostatic scaling parameter: nh_am2
222    o pkg/my82: futile attempt to make results compiler-independent by adding
223      some "_d 0", etc. no effect.
224    o for mnc output, fill the 'T' coordinate var with myTime and create a
225      separate 'iter' variable for iteration count
226    o pkg/diagnostics:
227      add new capability: output of Global/Regional & per-level statistics ;
228      tested against monitor output (including land & thSIce) on various exp.
229    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
230    
231    checkpoint57h_done
232      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
233      data.diagnostics, data.gchem, data.ptracers) is done.
234    
235    o pkg/diagnostics: prepare for Global/Regional statistics.
236      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
237    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
238      and rename it: DIFFERENT_MULTIPLE
239    
240    checkpoint57h_post
241    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
242    o pkg/diagnostics: change output frequency, now in seconds (instead
243      of Nb of iterations). This requires to change data.diagnostics.
244    checkpoint57h_pre
245    
246    o in mnc, let the user create the output dir if both mnc_outdir_date
247      and mnc_outdir_num are false
248    o add fflags() to pkg/diagnostics which allows one to specify, on a
249      per-file basis, the file precision [default behavior is unchanged]
250    o added diagnostics to pkg/kpp, including computation of mixed layer
251      depth based on a temperature/density criterion
252    o updated verification/natl_box to test the new pkg/kpp diagnostics
253    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
254    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
255    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
256      not mnc -- this mistake was found by JMC and is now corrected
257    
258    checkpoint57g_post
259    o add Adams-Bashforth 3rd Order time stepping:
260      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
261      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
262    checkpoint57g_pre
263    
264    o make lambda[Theta,Salt]ClimRelax spatially varying
265      (default remains spatially uniform constant based on tau)
266    o added new control variables
267      * init. uVel, vVel, etanN
268      * lambda[Theta,Salt]ClimRelax
269    o separate masks used for ctrl_pack/unpack 'from write_grid' output
270      (suggested by G. Forget)
271    
272    checkpoint57f_post
273    o add parameter "baseTime" = model base time = time at iteration zero
274      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
275      account for baseTime shift
276    o move Coriolis arrays from PARAMS.h to GRID.h
277    checkpoint57f_pre
278    
279    o mnc-ifying the seaice package
280    o introduced an alternative length scale calculation for use in the limiting
281      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
282    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
283    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
284      as well as grad(vort3).  Made it compatible with both approximate form
285      for the cubed sphere and full form of these gradients.  Added flag
286      useFullLeith to select between approximate and full form.  
287    o add "d0" in getcon.F to reduce differences between compilers/platforms
288      update output.txt of exp. fizhi-gridalt-hs
289    o change port_rand funtion to allow to set the seed.
290    o fix obscure MNC bug involving conversion between reals and integers
291      - it caused no problems with certain (eg. gcc, ifc) compilers but the
292        new version is now more standards-compliant
293    o adjoint-related modifications
294      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
295      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
296      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
297    
298    checkpoint57e_post
299    o Adding eddy stress controls a la Ferreira et al.
300    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
301    
302    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
303      update output.txt of exp. fizhi-gridalt-hs
304    o add more "Z" dimensions and associated coordinate vars to MNC
305    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
306    o parameter calendarDumps: when set, approximate months (30-31 days) and years
307      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
308      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
309      months and years.  Requires pkg/cal.
310    o diagnostics: add pickup functionality
311      - off by default for backwards compatibility
312      - current version only uses MDSIO -- MNC will be added
313    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
314    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
315    
316    checkpoint57d_post
317    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
318    o modify verification/ideal_2D_oce so that it tests the creation of mnc
319      output from the diagnostics package
320    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
321    o make genmake2 more portable by using ".$FS" instead of ".f" for more
322      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
323    o add coordinate variables to the MNC output from the diagnostics package
324    o change MNC-flags default value: true when useMNC=TRUE
325    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
326      the ability (off by default) to read the grid information using MNC
327    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
328    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
329    o do snap-shot diagnostics at the middle of the time-interval (instead of
330      at the end).
331    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
332      new test for AIM with thSIce + slab-ocean
333    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
334    o move state variable diagnostics to the beginning of the time step ;
335      (note: still needs some work specially for snap-shot diagnostics)
336      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
337    
338    checkpoint57c_post
339    o Change testing option (-ieee) to get closer agreement between g77 & ifort
340    o generate new output.txt files on faulks with g77 & the new -ieee option
341    checkpoint57c_pre
342    
343    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
344      update output.txt of exp. global_ocean.90x40x15
345    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
346      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
347    o add saltFlux(+File) forcing capability with periodicExternalForcing
348    o allow to use pkg diagnostics for GM-Redi & ThSIce output
349    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
350    o improvements for the MNC output from DIAGNOSTICS:
351      - correct handling of the unlimitied dimension
352      - all dims now have associated coordinate variables
353      - variables located at U, V, and Corner ("Z") points are now written
354        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
355        *all* data points are output
356    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
357    o added pkg/seaice/seaice_monitor.F
358    o mdsio_readfield.F can now read files visible only to master MPI process.
359    o pkg/seaice: some test code for ice-modified ocean stress
360    o exf_getffields interpolation defaults to bilinear for all scalar forcing
361      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
362      spurious negative numbers for precipitation and humidity.  Will cause
363      some small numerical differences for integrations using pkg/exf/exf_interp.F.
364    o pkg/ctrl/
365      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
366        May be enabled via doPackDiag
367      *  introduce z-scaling of
368         + gradient (doZscalePack) and
369         + control (doZscaleUnpack)
370    o pkg/mdsio/
371      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
372      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
