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