4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/sbo:
8      - incorporate modifications from Katherine Quinn to enable the use of sbo
9        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
10        output for future testreport verification (unfinished).
11    o pkg/atm_phys:
12      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
13        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
14        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
15    o pkg/seaice
16      seaice_calc_ice_strength.F: modify expression to avoid divisions
17        (affects truncation)
18      seaice_do_ridging.F: clean up the insectarium
19      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
20      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
21      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
22      - add some debugging information and error messages (warnings)
23    o model/src: modifications relatd to atmosphere p*:
24      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
25      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
26        of vertical profile tRef in geopotential background and anomaly.
27      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
28        and pkg/atm_phys.
29      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
30        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
31    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
32    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
33        not used right now, but can be used in BGC packages to fix conservation.
34    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
35        other packages too.
36    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
37        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
38    o model/src:
39      - since we have several heat capacity (even in model/src), define "recip_Cp"
40        as local variable (no longer in common block) to avoid any confusion.
41      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
42    o pkg/exf:
43      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
44        air density as function of air Temp, Humidity and atm pressure.
45    
46    checkpoint64w (2014/05/02)
47    o verification:
48      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
49        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
50        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
51        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
52        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
53    o model/src: for atmosphere in p* coords:
54      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
55      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
56        but not yet activated.
57    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
58      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
59      - this changes the results (but not for any verification experiment, because
60        none tests this), but avoids having an extra field in the restart files
61  o pkg/seaice: remove global variable TICE (not needed)  o pkg/seaice: remove global variable TICE (not needed)
62    - replace by TICES or local variable where necessary (cost_seaice_test,    - replace by TICES or local variable where necessary (cost_seaice_test,
63      seaice_diagnostics_state)      seaice_diagnostics_state)
64    - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup    - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
65    - use specific read/write routines for reading and writing individual leves    - use specific read/write routines for reading and writing individual leves
