4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/dic:
8      - add tons of "_d 0" (--> much better testreports !)
9       and then update outputs of tutorial_global_oce_biogeo
10    o pkg/mom_fluxform:
11      add a special version of momentum advection intended to conserve momentum
12      next to a bathymetry step or a coastline edge. (default = off = #undef)
13    o new read/write pickup version:
14      - for now, only implemented for main (mdsio) pickup file.
15      - write out only what is needed to restart; merge pickup_nh , pickup_ph
16        and main pickup together.
17      - read meta file; read only what is needed to restart; stop if a field
18        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
19        if it make sense (even if the restart is not perfect).
20      - if no meta file, assume that pickup to read corresponds exactly to
21        a pickup that would currently be written.
22      - read pickup written in the old format (until checkpoint59i) if it
23        recognizes an old meta file (no field-list).
24      - add a meta file in exp. which starts from a pickup: 2 cases:
25        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
26         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
27        b) a meta file describing the content of the associated pickup file
28         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
29    o pkg/mdsio & pkg/rw:
30      - new routine to read a meta file ; new set of routine to read
31        Multiple-fields file (with meta file).
32    o added open boundary conditions capability for seaice
33        HSNOW, HSALT, UICE, and VICE
34    
35    checkpoint59i
36    o adjoint:
37      * fix multiDimAdvection adjoint
38        (partial recomputation problem by TAF for fVerT(:,:,kDown)
39        and comlev1 size definition (maxpass vs. max. number of tracers)
40      * verification/global_ocean.90x45x15 adjoint now tests
41        NLFS and multiDimAdvection using DST3 (=30)
42      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
43    o pkg/kpp: add "_d 0" to real constant (if missing);
44      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
45      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
46    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
47      for internal parameters related to restart process (formerly from PARAMS.h)
48      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
49    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
50      as argument. (only atm2d & obcs write_pickup have not yet been updated)
51    o pkg/monitor:
52      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
53      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
54      - account for deep Atmosphere factor and density factor (anelastic)
55    o added open boundary conditions capability for seaice HEFF and AREA
56    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
57      thermodynamics
58      - requires a little reorganization, which affects the testreport results
59        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
60        so that now the conservative form is tested
61      - add a few comments
62    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
63    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
64    o add new diagnostics to seaice: advective, diffusive fluxes (only for
65      multidim-advection, for scheme 2 they are not filled) and transports,
66      thermodynamic growth rates
67    o change units of EmPmR (inside the code, + within coupling interface)
68      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
69      Affects results @ truncation level (cg2d match) and update output of
70       experiments: lab_sea(6), global_ocean.90x40x15(10),
71      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
72      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
73      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
74      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
75    
76    checkpoint59h
77    o pkg/exf:
78      - improve vectorization by moving if-statement out of loops in
79        exf_mapfields, exf_radiation
80      - exf_bulkformulae.F: introduce 2D fields and vectorize code
81    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
82    o testreport:
83      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
84        monitor & update offline_exf_seaice exp. output.
85      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
86    o pkg/seaice:
87      - bug fix in the evp solver: boundary conditions were affected be
88        masking of zMax/zMin (changes results)
89      - minor bug fix in boundary conditions in seaice_calc_strainrates
90        (changes results for no_slip)
91      - seaice_lsr.F: make interpolation of eta dependent on boundaries
92      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
93      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
94        stress formulation and no-slip boundary conditions
95    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
96      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
97    o pkg/seaice: a first HSALT time stepping equation has been checked in
98    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
99      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
100      without requiring DO-IF statements
101    o pkg/thsice:
102      use continuous power-law function for partition of energy between lateral
103      melting/freezing and thinning/thickening ; old code using step function
104      still available with #undef THSICE_FRACEN_POWERLAW
105      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
106    o testreport: change AD testing : check against results/output_adm.txt
107      using same scripts as for forward test.
108    
109    checkpoint59g
110    o adjoint testing: in preparation for changing testreport:
111      - output format: cost and grad written on separated lines
112      - ad output results in directory "results" (instead of "results_ad")
113  o pkg/seaice: adding ice salinity HSALT as a prognostic variable  o pkg/seaice: adding ice salinity HSALT as a prognostic variable
