9    o pkg/cheapaml:
10      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
11        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
12        with pkg/cheapaml.
13    o utils/python: add subpackage for cubed sphere function, first example is
14        simple cs.pcol to plot 2D fields on a map
15    o pkg/streamice:
16      - This is a new package in MITgcm, which solves dynamic equations for ice
17         sheets and ice streams
18      - At the moment it is independent of atmosphere/ocean dynamics, or any
19        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
20        ed that this will change)
21      - There is a new verification exercise that tests it, halfpipe_streamice,
22        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
23        rectangular embayment
24      - halfpipe_streamice is forward-only for now, will have TAF test soon
25      - for questions, email dgoldber@mit.edu
26    o pkg/thsice:
27      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
28        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
29      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
30         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
31      - allow precip from pkg/cheapaml to make snow over seaice.
32    o pkg/cfc:
33      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
34      - remove atmos CFC 2-D arrays from common bloc (now local variables)
35      - change some hard-coded constant to run time parameter for reading and
36        and interpolating atmospheric CFC ; keep same default as previously.
37      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
38      - put arguments in standard order: myTime, myIter, myThid
39      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
40        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
41      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
42      - new routine to print summary of CFC params and check for consistency.
43    o pkg/cfc:
44      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
45        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
46      - fix interpolation of atmphspheric CFC between Sorthern and Northern
47        hemisphere value.
48    o pkg/seaice:
49      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
50    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
51                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
52      - requires an additional time level that is stored in the pickup
53      - you can start with AB2 from a pickup without this time level with
54        pickupStrictlyMatch = .false.
55    
56    checkpoint64h (2013/05/26)
57    o pkg/cheapaml:
58      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
59        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
60      - consistent treatment of uWind,vWind location: assume everywhere in
61        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
62        (Note: was already the case for Tair,Qair advection);
63        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
64      - compute diabatic forcing only in the interior (excluding overlap regions)
65      - fill in array "Qsw" (for short-wave heating);
66      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
67        before any update (consistent with MITgcm state var diagnostics);
68      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
69        non periodic ; + adjusted for uWind,vWind (C-grid).
70    o pkg/seaice:
71      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
72        add explicitly pkg/exf in experiments that currently use pkg/seaice.
73      - allows to compile pkg/seaice without pkg/exf.
74    o tools/OAD_support:
75      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
76        of array "ourStepOf" in function rvNextAction (revolve.F90).
77    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
78      - change pkg name (to be used with other atmospheric physics pkg)
79        but by-pass CVS when making the new pkg so that we keep the CVS history.
80    o pkg/offline:
81      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
82        (previously called from pkg/dic_surfforcing_init.F)
83    o model/src:
84      - re-order sequence of calls within packages_init_variables.F, using
85        standard order, except for:
86         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
87         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
88  o new pkg: atm_phys  o new pkg: atm_phys
89    - add entry point for new pkg "atm_phys" (atmospheric physics pkg    - add entry point and source code (previously in contrib
90      from P. O'Gorman and T. Schneider, JCl, 2008).        verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
91        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
92    - re-order sequence of calls within packages_readparms.F,    - re-order sequence of calls within packages_readparms.F,
93       packages_init_fixed.F and packages_write_pickup.F       packages_init_fixed.F and packages_write_pickup.F
94      (but skip packages_init_variables.F because of TAF issues).      (but skip packages_init_variables.F because of TAF issues).
95      - update contrib/*/atm_gray/ experiment.
96  o pkg/seaice (ITD code):  o pkg/seaice (ITD code):
97    - simplify and fix the writing of pickup-files for ITD case    - simplify and fix the writing of pickup-files for ITD case
98  o pkg/seaice (ITD code):  o pkg/seaice (ITD code):
