4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o add a new package shelfice which enables us to model the circulation
8      underneath shelf-ice with draughts of hundreds of meters.
9     - works
10     - to do: + include improved thermodynamics
11              + check whether kSurfC (from model/inc/SURFACE.h) can be used
12                instead of new field kTopC
13              + can we use topoFile, Ro_surf and existing code in ini_depth.F
14                instead of new field R_shelfIce and new code in ini_depth.F
15                and ini_mask_etc.F?
16    o seaice pkg:
17     - add a cpp-flag to include a simple formula for a salinity dependent
18       freezing point of sea water at the surface
19     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
20       meridional stresses are now different (and hopefully correct)
21    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
22       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
23       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
24    o pkg/diagnostics: add options and parameters for regional-statistics
25       diagnostics ; define regions by reading a region-mask from a file
26       (might add other options later)
27    o pkg/bulk_force:
28     - add option and parameters to use AIM surface-flux formulae.
29     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
30       others forcing fields (defined in PARM05, parameter file "data") are loaded
31       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
32     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
33     - use the right EXCH call for uwind,vwind (to work on CS-grid).
34     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
35       and parameters (note: calcWindStress replaces .NOT.readwindstress).
36     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
37    
38    checkpoint58
39    o add "--embed-source" option to genmake2 which, when the supporting
40      tools can be compiled (as determined by genmake2) will turn on the
41      embed_files package which then embeds the entire MITgcm source code
42      (*.[fFhc] + Makefile) used for the build within the executable
43      - requested by CNH but off by default
44      - adds a paltry <9MB to the mitgcmuv executable in most cases
45      - only writes the output when useEMBEDSRC in eedata is true
46    o clean up 3-dim. relaxation codes:
47      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
48      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
49      * Thanks to Tom Haine for testing!
50    
51    checkpoint57z_post
52    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
53      affects output (@ truncation level) of exp. plume_on_slope ; updated.
54    o fix the pickup behavior for obcs in combination with ptracers
55    o fix a bug in ptracers_external_fields_load
56    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
57      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
58    o transfered surface NH pressure to eta field (if exactConserv).
59    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
60         and update lab_sea output.txt file.
61    o completing 3-dim. relaxation code: additional term
62         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
63      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
64      * At compile time, in "EXF_OPTIONS.h" set
65          #define  ALLOW_CLIMTEMP_RELAXATION
66          #define  ALLOW_CLIMSALT_RELAXATION
67      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
68          tauThetaClimRelax3Dim = 15552000.0,
69          tauSaltClimRelax3Dim  = 15552000.0,
70      * 3 cases:
71          1) Use a constant-in-time 3-dim. field
72          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
73          3) Real-time relax. to time-evolving prescribed field
74    o Adding Laplacian-type smoothness constraint on
75      initial and boundary (forcing) controls (ic, bc)
76      * enable at compile-time via
77        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
78      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
79      * Absolute scale somewhat unclear so far
80      * no area weighting was included since no other cost term does so far
81    
82  checkpoint57y_post  checkpoint57y_post
83  First step for a NLFS adjoint  First step for a NLFS adjoint
84  o initially suppress rStar (new flag DISABLE_RSTAR_CODE)  o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
