4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o verification/isomip, pkg/shelfic and OpenAD:  checkpoint64m (2013/08/13)
8    o model/inc:
9      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
10        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
11    o pkg/kpp & aim_v23:
12      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
13    o pkg/seaice:
14      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
15        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
16      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
17    o eesupp/src:
18      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
19        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
20    o switch to TAF version-2:
21      - add flow directives to "freeze" naming convention for ad-routines that
22        are used in I/O routines of adjoint state and associated common blocks
23        that are used in adcommon.h (backward compatible with version-1)
24      - update all ad-optfiles (in tools/adjoint_options + few local to some
25        verification exp) to switch to latest TAF version (currently 2.5.5);
26        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
27        out except for diva).
28      - the major change with TAF version-2 is that both the differentiated
29        routines and the forward routines (new) are returned as part of the TAF
30        output source code. Update genmake2 accordingly.
31      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
32        with version-2 when compared to TLM or FWD gradient); other experiments
33        output show minor changes (machine truncation level); update the few AD &
34        TLM output with 12 matching digits only (some prior to version-2 switch).
35    
36    checkpoint64l (2013/08/05)
37    o model/src:
38      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
39      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
40        when using TAF but only if using OpenAD.
41    o pkg/mom_common+fluxform+vecinv:
42      - always set horiz. viscosity arrays to background value before calling
43        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
44        only when using variable horiz. viscosity (useVariableVisc=T);
45      - simplify mom_vecinv.F (only 1 block for momViscosity).
46    o pkg/mom_common: variable horiz. viscosity in NH code
47      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
48        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
49      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
50        useBiharmonicVisc & useVariableVisc.
51      - fix old bug (already in 1rst implementation of variable horizontal viscosity
52        in calc_gw.F, version 1.27, 2006/06/20):
53        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
54        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
55      - change background horiz viscosity in vertical momentum (gW) to always be
56        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
57        any type of variable viscosity, e.g., viscAh/4Grid)
58      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
59        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
60        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
61        default viscAh,viscA4 is zero).
62    o model/src:
63      - extend length of drC & recip_drC from Nr to Nr+1.
64    o Divided Adjoint (DIVA) with MPI:
65      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
66      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
67        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
68    
69    checkpoint64k (2013/07/23)
70    o tools/OAD_support:
71      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
72        and remove it from genmake2.
73    o tools/build_options:
74      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
75        MPI_HEADER_FILES list (let genmake2 find the missing headers)
76    o verification/halfpipe_streamice:
77      - change to driving stress formulation; update both Fwd & AD output.
78    o tools/genmake2 and Divided Adjoint with MPI:
79      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
80      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
81      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
82        Makefile, which is set by genmake2, and check which mpi-headers are needed.
83        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
84      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
85    o testreport:
86      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
87        perform additional runs (number of additional runs is "add_DIVA_runs" taken
88        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
89    o verification/lab_sea (AD test):
90      - change to test Divided Adjoint Run in this set-up (both standard AD test
91        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
92    o pkg atm_ & ocn_compon_interf:
93      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
94        staggerTimeStep implementation) and disable (retired) corresponding
95        parameter.
96    o pkg/offline:
97      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
98      - add S/R OFFLINE_CHECK to print offline parameter summary
99        and stop if loading a file that is not used;
100      - enable to calculate GMRedi tensor, KPP mixing and convective index
101        when the corresponding file(s) is/are not specified (but pkg is used).
102      - comment out resetting of monitorFreq (to endTime) since it still useful
103        for monitoring CFL numbers and checking offline fields.
104    o OpenAD:
105      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
106        smaller standard output) and generate new (smaller) output (on baudelaire
107        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
108    o model/src:
109      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
110        (where external_forcing_adjust was called) and change list of arguments;
111      - merge external_forcing_adjust.F into external_forcing_surf.F
112      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
113        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
114        previously in file "balance_relax.F", now removed); remove corresponding
115        arrays in FFIELDS.h.
116      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
117        a hack for getting back surfaceForcingS (loaded from file) when using
118        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
119      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
120        (was getting only 11 digits for AD-grad, due to different truncation
121         error in AD code).
122    
123    checkpoint64j (2013/07/04)
124    o pkg/offline:
125      - to enable the use of other features with pkg offline (e.g., obcs),
126        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
127      - comment out "allowFreezing" (now active) in 2 offline testing exp.
128    o pkg/exf ALLOW_RUNOFTEMP
129      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
130      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
131      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
132    o pkg/atm_phys:
133      - allows to add some damping on uVel,vVel (strength only function of k).
134    o verification, ad-tests:
135      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
136        global_ocean_ebm and offline_exf_seaice.thsice.
137    o verification/halfpipe_streamice:
138      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
139        flux input boundary conditions to be ignored; a fix for this bug changed
140        verification results for forward test.
141      - add adjoint test.
142    o pkg/ptracers:
143      - allow to restart without SOM pickup (resetting SOM to zero).
144    o pkg/gmredi:
145      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
146      - It uses mixing length theory and suppression by steering level effects to
147        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
148        to JPO, for more details).
149      - It also uses the diffusivity to calculate an eddy induced streamfunction
150        based on a PV closure (rather than a buoyancy closure as in GM).
151      - New files added to pkg/gmredi:
152        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
153          induced overturning streamfunction (called from gmredi_calc_tensor)
154        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
155          for use in gmredi_k3d
156        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
157          the eddy diffusivity
158    
159    checkpoint64i (2013/06/18)
160    o pkg/cheapaml:
161      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
162        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
163        with pkg/cheapaml.
164    o utils/python: add subpackage for cubed sphere function, first example is
165        simple cs.pcol to plot 2D fields on a map
166    o pkg/streamice:
167      - This is a new package in MITgcm, which solves dynamic equations for ice
168         sheets and ice streams
169      - At the moment it is independent of atmosphere/ocean dynamics, or any
170        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
171        ed that this will change)
172      - There is a new verification exercise that tests it, halfpipe_streamice,
173        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
174        rectangular embayment
175      - halfpipe_streamice is forward-only for now, will have TAF test soon
176      - for questions, email dgoldber@mit.edu
177    o pkg/thsice:
178      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
179        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
180      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
181         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
182      - allow precip from pkg/cheapaml to make snow over seaice.
183    o pkg/cfc:
184      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
185      - remove atmos CFC 2-D arrays from common bloc (now local variables)
186      - change some hard-coded constant to run time parameter for reading and
187        and interpolating atmospheric CFC ; keep same default as previously.
188      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
189      - put arguments in standard order: myTime, myIter, myThid
190      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
191        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
192      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
193      - new routine to print summary of CFC params and check for consistency.
194    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
195      similar to thsice_advdiff.
196      Note that for the B-grid case the routine parameters uc/vc are overwritten.
197    o pkg/cfc:
198      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
199        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
200      - fix interpolation of atmphspheric CFC between Sorthern and Northern
201        hemisphere value.
202    o pkg/seaice:
203      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
204    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
205                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
206      - requires an additional time level that is stored in the pickup
207      - you can start with AB2 from a pickup without this time level with
208        pickupStrictlyMatch = .false.
209    
210    checkpoint64h (2013/05/26)
211    o pkg/cheapaml:
212      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
213        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
214      - consistent treatment of uWind,vWind location: assume everywhere in
215        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
216        (Note: was already the case for Tair,Qair advection);
217        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
218      - compute diabatic forcing only in the interior (excluding overlap regions)
219      - fill in array "Qsw" (for short-wave heating);
220      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
221        before any update (consistent with MITgcm state var diagnostics);
222      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
223        non periodic ; + adjusted for uWind,vWind (C-grid).
224    o pkg/seaice:
225      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
226        add explicitly pkg/exf in experiments that currently use pkg/seaice.
227      - allows to compile pkg/seaice without pkg/exf.
228    o tools/OAD_support:
229      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
230        of array "ourStepOf" in function rvNextAction (revolve.F90).
231    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
232      - change pkg name (to be used with other atmospheric physics pkg)
233        but by-pass CVS when making the new pkg so that we keep the CVS history.
234    o pkg/offline:
235      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
236        (previously called from pkg/dic_surfforcing_init.F)
237    o model/src:
238      - re-order sequence of calls within packages_init_variables.F, using
239        standard order, except for:
240         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
241         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
242    o new pkg: atm_phys
243      - add entry point and source code (previously in contrib
244          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
245        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
246      - re-order sequence of calls within packages_readparms.F,
247         packages_init_fixed.F and packages_write_pickup.F
248        (but skip packages_init_variables.F because of TAF issues).
249      - update contrib/*/atm_gray/ experiment.
250    o pkg/seaice (ITD code):
251      - simplify and fix the writing of pickup-files for ITD case
252    o pkg/seaice (ITD code):
253      - introduce floe size dependent lateral melt for ITD case;
254      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
255      - update seaice_itd experiment main output.
256    o pkg/thsice:
257      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
258        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
259        changed accordingly pkg/atm2d.
260    
261    checkpoint64g (2013/05/01)
262    o pkg/exf ALLOW_RUNOFTEMP
263      - if defined,  river and glacier runoff temperature can be read-in from
264        runoftempfile; runoftempfile needs to have same format as runofffile
265    o pkg/thsice (& pkg/bulk_force):
266      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
267        for energy content of Precip + RunOff & Evap (like with pkg/exf).
268      - change computation domain to always be the interior (without overlap).
269      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
270    o verification/tutorial_global_oce_biogeo:
271      - add preliminary OpenAD setup (still has problems)
272    o pkg/seaice:
273      - turn some parameters for choosing the convergence criterion of
274        the inexact Newton method (JFNK) into runtime parameters for convenience
275      - clean up seaice_calc_viscosities.F: remove/retire two options for
276        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
277        the results of lab_sea/input because a division has been replaced by
278        a multiplication with the reciprocal (sumNorm)
279      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
280        convergence of solver (changes results, of course), and to test some
281        new features
282    o model/src:
283      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
284      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
285      - move forcing adjustment (balancing surface forcing) in specific S/R
286        where might also be applied exchanges (if needed) to forcing arrays.
287    o pkg/shelfice:
288      - allow to specify the Ice-Shelf mass per unit area (instead of
289        shelficeLoadAnomaly) and do the conversion from one to the other
290      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
291        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
292        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
293        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
294      - update isomip experiment forward output (get machine truncation error
295        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
296    o verification/offline_exf_seaice:
297      revise data.seaice in input.thermo and input_ad and update results accordingly
298        HO = 0.2, SEAICE_areaLossFormula = 2,
299        SEAICE_growMeltByConv = .TRUE.,
300        SEAICE_doOpenWaterMelt = .TRUE.,
301      Improve consistency with input.thsice and fix the spurious 500m ice corners
302    o verification/global_ocean.cs32x15:
303      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
304        in icedyn (thsice+seaice-dyn) test and update output.
305    o verification/offline_exf_seaice:
306      - adjust list of tested variables (with testreport) and update
307        standard test output with better slection of monitored fields.
308    o pkg/cd_code:
309      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
310        experiment lab_sea.hb87
311    o tools/genmake2:
312      - change default makedepend from the system default to tools/xmakedepend:
313        When no makedepend is specified, select tools/xmakedepend it the test pass,
314        otherwise select the system default (if exist and pass the test) or
315        try to build cyrus-makedepend ; stop if none of the 3 works.
316    o pkg/exf & pkg/thsice:
317      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
318        for energy content of Precip + RunOff & Evap. Assumes:
319       1) Rain has same temp as Air.
320       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
321       3) Run-Off comes at the temp of surface water (with same Cp)
322       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
323        put directly into Latent Heat flux & should use water-vapor heat capacity.
324       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
325        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
326    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
327        (compile when SEAICE_ALLOW_JFNK is defined)
328    o pkg/thsice:
329      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
330        implementation): move THSICE_AVE call after the advection (called directly
331        from thsice_do_advect.F).
332    o verification/global_ocean.90x40x15 and OpenAD:
333      New experiment for OpenAD is identical to the one in input_ad except that
334        multiDimAdvection=.FALSE.,
335      There is still an issue with this.
336    o pkg/thsice:
337      - account for ice velocity (ocean relative velocity) in turbulent heat flux
338        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
