5      ==============================      ==============================
6    
7    o pkg/mom_common: variable horiz. viscosity in NH code
8      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
9        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
10      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
11        useBiharmonicVisc & useVariableVisc.
12      - fix old bug (already in 1rst implementation of variable horizontal viscosity
13        in calc_gw.F, version 1.27, 2006/06/20):
14        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
15        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
16      - change background horiz viscosity in vertical momentum (gW) to always be
17        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
18        any type of variable viscosity, e.g., viscAh/4Grid)
19      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
20        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
21        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
22        default viscAh,viscA4 is zero).
23    o model/src:
24      - extend length of drC & recip_drC from Nr to Nr+1.
25    o Divided Adjoint (DIVA) with MPI:
26      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
27      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
28        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
29    
30    checkpoint64k (2013/07/23)
31    o tools/OAD_support:
32      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
33        and remove it from genmake2.
34    o tools/build_options:
35      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
36        MPI_HEADER_FILES list (let genmake2 find the missing headers)
37    o verification/halfpipe_streamice:
38      - change to driving stress formulation; update both Fwd & AD output.
39    o tools/genmake2 and Divided Adjoint with MPI:
40      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
41      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
42      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
43        Makefile, which is set by genmake2, and check which mpi-headers are needed.
44        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
45      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
46    o testreport:
47      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
48        perform additional runs (number of additional runs is "add_DIVA_runs" taken
49        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
50    o verification/lab_sea (AD test):
51      - change to test Divided Adjoint Run in this set-up (both standard AD test
52        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
53    o pkg atm_ & ocn_compon_interf:
54      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
55        staggerTimeStep implementation) and disable (retired) corresponding
56        parameter.
57    o pkg/offline:
58      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
59      - add S/R OFFLINE_CHECK to print offline parameter summary
60        and stop if loading a file that is not used;
61      - enable to calculate GMRedi tensor, KPP mixing and convective index
62        when the corresponding file(s) is/are not specified (but pkg is used).
63      - comment out resetting of monitorFreq (to endTime) since it still useful
64        for monitoring CFL numbers and checking offline fields.
65    o OpenAD:
66      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
67        smaller standard output) and generate new (smaller) output (on baudelaire
68        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
69    o model/src:
70      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
71        (where external_forcing_adjust was called) and change list of arguments;
72      - merge external_forcing_adjust.F into external_forcing_surf.F
73      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
74        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
75        previously in file "balance_relax.F", now removed); remove corresponding
76        arrays in FFIELDS.h.
77      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
78        a hack for getting back surfaceForcingS (loaded from file) when using
79        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
80      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
81        (was getting only 11 digits for AD-grad, due to different truncation
82         error in AD code).
83    
84    checkpoint64j (2013/07/04)
85    o pkg/offline:
86      - to enable the use of other features with pkg offline (e.g., obcs),
87        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
88      - comment out "allowFreezing" (now active) in 2 offline testing exp.
89    o pkg/exf ALLOW_RUNOFTEMP
90      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
91      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
92      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
93    o pkg/atm_phys:
94      - allows to add some damping on uVel,vVel (strength only function of k).
95    o verification, ad-tests:
96      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
97        global_ocean_ebm and offline_exf_seaice.thsice.
98    o verification/halfpipe_streamice:
99      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
100        flux input boundary conditions to be ignored; a fix for this bug changed
101        verification results for forward test.
102      - add adjoint test.
103    o pkg/ptracers:
104      - allow to restart without SOM pickup (resetting SOM to zero).
105    o pkg/gmredi:
106      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
107      - It uses mixing length theory and suppression by steering level effects to
108        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
109        to JPO, for more details).
110      - It also uses the diffusivity to calculate an eddy induced streamfunction
111        based on a PV closure (rather than a buoyancy closure as in GM).
112      - New files added to pkg/gmredi:
113        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
114          induced overturning streamfunction (called from gmredi_calc_tensor)
115        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
116          for use in gmredi_k3d
117        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
118          the eddy diffusivity
119    
120    checkpoint64i (2013/06/18)
121    o pkg/cheapaml:
122      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
123        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
124        with pkg/cheapaml.
125    o utils/python: add subpackage for cubed sphere function, first example is
126        simple cs.pcol to plot 2D fields on a map
127    o pkg/streamice:
128      - This is a new package in MITgcm, which solves dynamic equations for ice
129         sheets and ice streams
130      - At the moment it is independent of atmosphere/ocean dynamics, or any
131        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
132        ed that this will change)
133      - There is a new verification exercise that tests it, halfpipe_streamice,
134        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
135        rectangular embayment
136      - halfpipe_streamice is forward-only for now, will have TAF test soon
137      - for questions, email dgoldber@mit.edu
138    o pkg/thsice:
139      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
140        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
141      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
142         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
143      - allow precip from pkg/cheapaml to make snow over seaice.
144    o pkg/cfc:
145      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
146      - remove atmos CFC 2-D arrays from common bloc (now local variables)
147      - change some hard-coded constant to run time parameter for reading and
148        and interpolating atmospheric CFC ; keep same default as previously.
149      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
150      - put arguments in standard order: myTime, myIter, myThid
151      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
152        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
153      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
154      - new routine to print summary of CFC params and check for consistency.
155    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
156      similar to thsice_advdiff.
157      Note that for the B-grid case the routine parameters uc/vc are overwritten.
158    o pkg/cfc:
159      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
160        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
161      - fix interpolation of atmphspheric CFC between Sorthern and Northern
162        hemisphere value.
163    o pkg/seaice:
164      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
165    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
166                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
167      - requires an additional time level that is stored in the pickup
168      - you can start with AB2 from a pickup without this time level with
169        pickupStrictlyMatch = .false.
170    
171    checkpoint64h (2013/05/26)
172    o pkg/cheapaml:
173      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
174        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
175      - consistent treatment of uWind,vWind location: assume everywhere in
176        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
177        (Note: was already the case for Tair,Qair advection);
178        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
179      - compute diabatic forcing only in the interior (excluding overlap regions)
180      - fill in array "Qsw" (for short-wave heating);
181      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
182        before any update (consistent with MITgcm state var diagnostics);
183      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
184        non periodic ; + adjusted for uWind,vWind (C-grid).
185    o pkg/seaice:
186      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
187        add explicitly pkg/exf in experiments that currently use pkg/seaice.
188      - allows to compile pkg/seaice without pkg/exf.
189    o tools/OAD_support:
190      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
191        of array "ourStepOf" in function rvNextAction (revolve.F90).
192    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
193      - change pkg name (to be used with other atmospheric physics pkg)
194        but by-pass CVS when making the new pkg so that we keep the CVS history.
195    o pkg/offline:
196      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
197        (previously called from pkg/dic_surfforcing_init.F)
198    o model/src:
199      - re-order sequence of calls within packages_init_variables.F, using
200        standard order, except for:
201         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
202         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
203    o new pkg: atm_phys
204      - add entry point and source code (previously in contrib
205          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
206        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
207      - re-order sequence of calls within packages_readparms.F,
208         packages_init_fixed.F and packages_write_pickup.F
209        (but skip packages_init_variables.F because of TAF issues).
210      - update contrib/*/atm_gray/ experiment.
211    o pkg/seaice (ITD code):
212      - simplify and fix the writing of pickup-files for ITD case
213    o pkg/seaice (ITD code):
214      - introduce floe size dependent lateral melt for ITD case;
215      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
216      - update seaice_itd experiment main output.
217    o pkg/thsice:
218      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
219        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
220        changed accordingly pkg/atm2d.
221    
222    checkpoint64g (2013/05/01)
223    o pkg/exf ALLOW_RUNOFTEMP
224      - if defined,  river and glacier runoff temperature can be read-in from
225        runoftempfile; runoftempfile needs to have same format as runofffile
226    o pkg/thsice (& pkg/bulk_force):
227      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
228        for energy content of Precip + RunOff & Evap (like with pkg/exf).
229      - change computation domain to always be the interior (without overlap).
230      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
231    o verification/tutorial_global_oce_biogeo:
232      - add preliminary OpenAD setup (still has problems)
233    o pkg/seaice:
234      - turn some parameters for choosing the convergence criterion of
235        the inexact Newton method (JFNK) into runtime parameters for convenience
236      - clean up seaice_calc_viscosities.F: remove/retire two options for
237        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
238        the results of lab_sea/input because a division has been replaced by
239        a multiplication with the reciprocal (sumNorm)
240      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
241        convergence of solver (changes results, of course), and to test some
242        new features
243    o model/src:
244      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
245      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
246      - move forcing adjustment (balancing surface forcing) in specific S/R
247        where might also be applied exchanges (if needed) to forcing arrays.
248    o pkg/shelfice:
249      - allow to specify the Ice-Shelf mass per unit area (instead of
250        shelficeLoadAnomaly) and do the conversion from one to the other
251      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
252        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
253        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
254        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
255      - update isomip experiment forward output (get machine truncation error
256        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
257    o verification/offline_exf_seaice:
258      revise data.seaice in input.thermo and input_ad and update results accordingly
259        HO = 0.2, SEAICE_areaLossFormula = 2,
260        SEAICE_growMeltByConv = .TRUE.,
261        SEAICE_doOpenWaterMelt = .TRUE.,
262      Improve consistency with input.thsice and fix the spurious 500m ice corners
263    o verification/global_ocean.cs32x15:
264      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
265        in icedyn (thsice+seaice-dyn) test and update output.
266    o verification/offline_exf_seaice:
267      - adjust list of tested variables (with testreport) and update
268        standard test output with better slection of monitored fields.
269    o pkg/cd_code:
270      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
271        experiment lab_sea.hb87
272    o tools/genmake2:
273      - change default makedepend from the system default to tools/xmakedepend:
274        When no makedepend is specified, select tools/xmakedepend it the test pass,
275        otherwise select the system default (if exist and pass the test) or
276        try to build cyrus-makedepend ; stop if none of the 3 works.
277    o pkg/exf & pkg/thsice:
278      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
279        for energy content of Precip + RunOff & Evap. Assumes:
280       1) Rain has same temp as Air.
281       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
282       3) Run-Off comes at the temp of surface water (with same Cp)
283       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
284        put directly into Latent Heat flux & should use water-vapor heat capacity.
285       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
286        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
287    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
288        (compile when SEAICE_ALLOW_JFNK is defined)
289    o pkg/thsice:
290      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
291        implementation): move THSICE_AVE call after the advection (called directly
292        from thsice_do_advect.F).
293    o verification/global_ocean.90x40x15 and OpenAD:
294      New experiment for OpenAD is identical to the one in input_ad except that
295        multiDimAdvection=.FALSE.,
296      There is still an issue with this.
297    o pkg/thsice:
298      - account for ice velocity (ocean relative velocity) in turbulent heat flux
299        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
300        and offline_exf_seaice (main test).
301    
302    checkpoint64f (2013/03/31)
303    o verification/OpenAD:
304      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
305    o verification/isomip, pkg/shelfice and OpenAD:
306      - add OpenAD setup to this exp and make shelfice package work with OpenAD
307    o verification/tutorial_global_oce_biogeo:
308      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
309    o verification/offline_exf_seaice:
310      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
311    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
312      - add OpenAD setup to this exp and make ptracers package work with OpenAD
313    o pkg/seaice/seaice_evp.F:
314       mask the asymmetric contribution of the ice-ocean stress (when
315       the turningAngle is non-zero) over open water to avoid stripes
316       in the EVP-solutions after many EVP-substeps. This does not change
317       the verification experiment (because turningAngle=0 in that experiment),
318       but will affect other EVP solutions with turningAngle.ne.0
319  o verification, AD & TLM output:  o verification, AD & TLM output:
320    - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple    - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
321      additions and multiplications which affect results at machine truncation      additions and multiplications which affect results at machine truncation
