3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
7      this does not change any of the results, because myIter=0 in swfrac always
8      lead to jwtype=2 (the default anyway), but the call makes little sense
9      as a default
10    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
11    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
12      atmospheric model (AIM) to use it ; add a "slab ocean" component.
13    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
14    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
15    o extending useSingleCpuIO option to work with new exch2 I/O format
16      - old-style, missing-tile I/O is still accessible by defining CPP
17        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
18    o monitor package can write to NetCDF files and/or STDOUT
19    o fix re-definition bug in MNC_GRID_INIT_ALL()
20    o doc/api_reference added
21      - a framework for building an API Reference Manual using all
22        the "protex" comments embedded in the code
23      - see pkg/generic_advdiff, pkg/mnc for examples
24    o MNC:
25      - make myThid the last argument for all subroutines
26      - new default for the grid files: NO halos
27      - add useMNC and other run-time flags
28      - separate per-file-group handling of the unlimited dimension
29      - early initialization of MNC w/ flags read at the eeboot stage
30        and lookup tables set in initialize_fixed
31      - write all MNC output to a freshly-created directory
32    o thermodynamics sea-ice (thsice) is now tested with testreport.
33    o test exp. advect_cs: use the standard cs32 grid ; update output.
34    o Added functionality to grdchk:
35      pick global i,j,k position (or nearest wet) where to perform check.
36    
37  untagged  checkpoint52l_post
38    o new land formulation:
39      a) use ground enthalpy as prognostic variable to ensure exact
40         energy conservation.
41      b) account for water temperature and for latent heat of freezing
42         in all processes (rain, run-off, ground storage)
43      c) compute surface and ground temperature implicitly.
44    o aim_v23 modification for new land model:
45      a) Treat separately land / ocean / sea-ice surface fluxes
46         to allow implicit computation of land & sea-ice surface temp.
47      b) add snow precipitation.
48    checkpoint52l_pre
49    
50    o fix problem (when 1 tile is empty) in min/max monitor.
51    o fix bug in timeAve (u,vZetatave in common block)
52    o no restoring terms under ice for pkg/seaice
53    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
54    o bug fix for pkg/seaice pickups
55    o change MNC call locations and add coordinate attributes
56    o mask vorticity at the corner ; affects global_ocean.cs output
57    o fix ini_curvilinear_grid ; test CS experiments with mpi
58    o aim.5l_cs: modify sea-ice fraction input file ; update output
59    o exf: Adding simple range check routine for exf fields after read
60    
61    checkpoint52k_post
62    o removed top-level directory "diags"
63      - we migrated these functions to pkg/timeave a long time ago
64    o fixed bug introduced in pkg/monitor
65    o accuracy ctrlprec = 32 insuffient for gradient checks using
66      averaged fields (I/O via cost_averages)
67      -> use ctrl.h in active_file*.F to control I/O precision.
68    o paramter list of CALL ADTHE_MAIN_LOOP
69    o added initial do_the_model_io to ecco
70    o set all ...Freq to zero after cost_final
71      taveFreq, dumpFreq, pChkptFreq
72    o MAIN and ECCO differentiability restored
73    
74    checkpoint52j_post
75    o fix nchklev in tamc.h for global_ocean...
76    o Bringing flow and store directives up-to-date
77    o Really weird thing!
78      call do_the_model_io from the_main_loop with parameters
79      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
80      TAF places a faulty re-call of initialise_varia
81      after cost_final call which should not be there!
82    checkpoint52j_pre
83    
84    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
85      error messages
86    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
87    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
88      debug output
89    o modfied mdsio_writefield.F to handle non-global files under exch2
90    o update AIM Cubed-Sphere exp (aim.5l_cs):
91      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
92    o update AIM Equatorial Channel exp:
93      use standard aim_v23 pkg and change the SST fields to be more realistic.
94    o globalFile now works with exch2
95    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
96      mon_vort3.F to make exch2 friendly with >1 tile per cube face
97    o limit timeave output for hi-res integrations
98    
99    checkpoint52i_post
100    o removed CPP_EEOPTIONS.h from verification/*/code
101    o updated the tiling for global_ocean_pressure
102    checkpoint52i_pre
103    
104    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
105      the old pkg/aim).
106    
107    checkpoint52h_pre
108    o shortened offending lines in exch2_send_rx?.template
109    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
110    o genmake2: add build & execute test for NetCDF code
111    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
112      old grid files, moved CPP_EEMACROS.h to pkg/exch2
113    o added useSingleCPUIO flag to monitor.F and mon_out.F
114    o added temporary hack for sea-ice dynamics on the cube:
115      metric terms are ignored and it is assumed that
116      there is no sea-ice on cube faces 1, 2, 4, and 5.
117    
118    checkpoint52f_post
119    o added exch2 cube routines to pkg/exch2
120    o modified hs94.cs-32x32x5 to use it
121    o added new grid files to hs94.cs-32x32x5
122    checkpoint52f_pre
123    
124    checkpoint52e_post
125    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
126      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
127    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
128      to work with implicit vertical advection and AB ;
129    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
130    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
131     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
132    checkpoint52e_pre
133    
134    o fix bug in impldiff when Nr=1 or Nr=2.
135    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
136    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
137    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
138      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
139    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
140    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
141    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
142    
143    checkpoint52d_post
144    o re-tiled many expts to allow comparison in multi-processor mode
145      - updated output accordingly
146      - changed hs94.128x64x5 to use intial T from file rather than use the
147        random number generator
148    o add infrastructure in model routines for fizhi and gridalt packages
149    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
150    o changes to permit hi-res, cubed-sphere, configuration
151      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
152      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
153      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
154        of surface winds for the cube
155      (A verification experiment, based on global_ocean.cs32x15, but with
156       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
157       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
158       complete with example surface forcing files and matlab scripts to look
159       at the output and compare it with that of global_ocean.cs32x15.)
160    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
161       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
162       to conform to the common rule.
163    o check-in the first version of the coupler + interfaces for multi-components
164       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
165       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
166       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
167       - ocean and atmos. share the same horizontal grid (no interpolation).
168       - exchanges between component and coupler is done in forward_step
169    o new verification experiment, cpl_aim+ocn:
170       coupled ocean - AIM atmosphere on cs32 grid.
171    
172    checkpoint52d_pre
173    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
174    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
175    
176    checkpoint52c_post
177    o Fixing OPTIONS files for use of exf:
178      - ALLOW_ECCO not needed
179      - ECCO_CPPOPTIONS.h should not be included from
180        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
181        as has been the case in the past
182      - All cal/exf related options are currently set in
183        single header file. Should remain so until we
184        agree on a consistent new policy.
185    o Removed all CPP options for cal package.
186      cal has no more CPP options.
187    o modified STOREs in GAD_ADVECTION
188    o corrected key comp. for passkey
189    
190    checkpoint52b_post
191    o new version: "thsice" of thermodynamic sea-ice pkg:
192     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
193     - modify fluxes but do not change theta directly;
194     - light cleaning of bulk_force pkg (still needed with thsice).
195     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
196       + output_thsice.txt to test thsice & bulk_force pkgs.
197    o put back grid & coriolis monitor output.
198    checkpoint52b_pre
199    
200    o call "do_the_model_io" at the beginning (=> dump initial state)
201    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
202    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
203      (need info on NUMBER_OF_PTRACERS)
204    o missing PTRACERS headers in some routines
205    o default tamc.h in pkg/autodiff supposed to crash
206      to ensure proper customization
207    
208    checkpoint52a_post
209    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
210      - moved surfaceTendencyTice from pkg/seaice to main code
211      - subroutine FREEZE_SURFACE now limits only surface temperature
212        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
213        => new output.txt for global_ocean.cs32x15 & global_with_exf
214      - keep the old version of FREEZE for backward compatibility;
215        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
216      - corresponding modifs for TAF directives
217    o added surface flux output variables to TIMEAVE_STATVARS
218    o time-averaged output for pkg/ptracers
219    o fix problem with ECCO-related divided adjoint
220      snapshot file was missing some ad-variables,
221      but no warning issued by TAF
222    
223    checkpoint52a_pre
224  o some bug fixes for #undef REAL4_IS_SLOW  o some bug fixes for #undef REAL4_IS_SLOW
225    
226  checkpoint52 = ecco_c52_e35  checkpoint52 = ecco_c52_e35
