4      ==============================      ==============================
5    
6    checkpoint52e_pre
7    o added exch2 cube routines to pkg/exch2
8    o modified hs94.cs-32x32x5 to use it
9    o added new grid files to hs94.cs-32x32x5
10    checkpoint52e_post
11    
12    checkpoint52e_post
13    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
14      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
15    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
16      to work with implicit vertical advection and AB ;
17    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
18    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
19     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
20    checkpoint52e_pre
21    
22    o fix bug in impldiff when Nr=1 or Nr=2.
23    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
24    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
25    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
26      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
27    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
28    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
29    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
30    
31    checkpoint52d_post
32    o re-tiled many expts to allow comparison in multi-processor mode
33      - updated output accordingly
34      - changed hs94.128x64x5 to use intial T from file rather than use the
35        random number generator
36    o add infrastructure in model routines for fizhi and gridalt packages
37    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
38    o changes to permit hi-res, cubed-sphere, configuration
39      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
40      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
41      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
42        of surface winds for the cube
43      (A verification experiment, based on global_ocean.cs32x15, but with
44       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
45       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
46       complete with example surface forcing files and matlab scripts to look
47       at the output and compare it with that of global_ocean.cs32x15.)
48    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
49       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
50       to conform to the common rule.
51    o check-in the first version of the coupler + interfaces for multi-components
52       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
53       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
54       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
55       - ocean and atmos. share the same horizontal grid (no interpolation).
56       - exchanges between component and coupler is done in forward_step
57    o new verification experiment, cpl_aim+ocn:
58       coupled ocean - AIM atmosphere on cs32 grid.
59    
60    checkpoint52d_pre
61    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
62    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
63    
64    checkpoint52c_post
65    o Fixing OPTIONS files for use of exf:
66      - ALLOW_ECCO not needed
67      - ECCO_CPPOPTIONS.h should not be included from
68        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
69        as has been the case in the past
70      - All cal/exf related options are currently set in
71        single header file. Should remain so until we
72        agree on a consistent new policy.
73    o Removed all CPP options for cal package.
74      cal has no more CPP options.
75    o modified STOREs in GAD_ADVECTION
76    o corrected key comp. for passkey
77    
78    checkpoint52b_post
79    o new version: "thsice" of thermodynamic sea-ice pkg:
80     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
81     - modify fluxes but do not change theta directly;
82     - light cleaning of bulk_force pkg (still needed with thsice).
83     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
84       + output_thsice.txt to test thsice & bulk_force pkgs.
85    o put back grid & coriolis monitor output.
86    checkpoint52b_pre
87    
88    o call "do_the_model_io" at the beginning (=> dump initial state)
89    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
90    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
91      (need info on NUMBER_OF_PTRACERS)
92    o missing PTRACERS headers in some routines
93    o default tamc.h in pkg/autodiff supposed to crash
94      to ensure proper customization
95    
96    checkpoint52a_post
97    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
98      - moved surfaceTendencyTice from pkg/seaice to main code
99      - subroutine FREEZE_SURFACE now limits only surface temperature
100        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
101        => new output.txt for global_ocean.cs32x15 & global_with_exf
102      - keep the old version of FREEZE for backward compatibility;
103        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
104      - corresponding modifs for TAF directives
105    o added surface flux output variables to TIMEAVE_STATVARS
106    o time-averaged output for pkg/ptracers
107    o fix problem with ECCO-related divided adjoint
108      snapshot file was missing some ad-variables,
109      but no warning issued by TAF
110    
111    checkpoint52a_pre
112    o some bug fixes for #undef REAL4_IS_SLOW
113    
114    checkpoint52 = ecco_c52_e35
115    o after testing adjoints of checkpoint51u_post
116    
117  checkpoint51u_post  checkpoint51u_post
118  o this is the post-merge tag of the ecco-branch  o this is the post-merge tag of the ecco-branch
119    (needs another clean checkout and re-testing)    (needs another clean checkout and re-testing)
