     Notes on tags used in MITgcmUV
     ==============================
 
+checkpoint64i (2013/06/18)
+o pkg/cheapaml:
+  - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
+    that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
+    with pkg/cheapaml.
+o utils/python: add subpackage for cubed sphere function, first example is
+    simple cs.pcol to plot 2D fields on a map
+o pkg/streamice:
+  - This is a new package in MITgcm, which solves dynamic equations for ice
+     sheets and ice streams
+  - At the moment it is independent of atmosphere/ocean dynamics, or any
+    other physical packages in MITgcm, even ShelfIce (although it is anticipat-
+    ed that this will change)
+  - There is a new verification exercise that tests it, halfpipe_streamice,
+    evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
+    rectangular embayment
+  - halfpipe_streamice is forward-only for now, will have TAF test soon
+  - for questions, email dgoldber@mit.edu
+o pkg/thsice:
+  - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
+    of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
+  - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
+     call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
+  - allow precip from pkg/cheapaml to make snow over seaice.
+o pkg/cfc:
+  - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
+  - remove atmos CFC 2-D arrays from common bloc (now local variables)
+  - change some hard-coded constant to run time parameter for reading and
+    and interpolating atmospheric CFC ; keep same default as previously.
+  - more flexible reading of Atmos CFC (number of records no longer hard-coded)
+  - put arguments in standard order: myTime, myIter, myThid
+  - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
+    atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
+  - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
+  - new routine to print summary of CFC params and check for consistency.
+o pkg/cfc:
+  - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
+    update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
+  - fix interpolation of atmphspheric CFC between Sorthern and Northern
+    hemisphere value.
+o pkg/seaice:
+  - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
+o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
+              so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
+  - requires an additional time level that is stored in the pickup
+  - you can start with AB2 from a pickup without this time level with
+    pickupStrictlyMatch = .false.
+
+checkpoint64h (2013/05/26)
+o pkg/cheapaml:
+  - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
+    affect machine truncation (but exp cheapAML_box still pass with 13 digits).
+  - consistent treatment of uWind,vWind location: assume everywhere in
+    pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
+    (Note: was already the case for Tair,Qair advection);
+    add option (INCONSISTENT_WIND_LOCATION) to recover old results.
+  - compute diabatic forcing only in the interior (excluding overlap regions)
+  - fill in array "Qsw" (for short-wave heating);
+  - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
+    before any update (consistent with MITgcm state var diagnostics);
+  - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
+    non periodic ; + adjusted for uWind,vWind (C-grid).
+o pkg/seaice:
+  - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
+    add explicitly pkg/exf in experiments that currently use pkg/seaice.
+  - allows to compile pkg/seaice without pkg/exf.
+o tools/OAD_support:
+  - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
+    of array "ourStepOf" in function rvNextAction (revolve.F90).
+o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
+  - change pkg name (to be used with other atmospheric physics pkg)
+    but by-pass CVS when making the new pkg so that we keep the CVS history.
+o pkg/offline:
+  - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
+    (previously called from pkg/dic_surfforcing_init.F)
+o model/src:
+  - re-order sequence of calls within packages_init_variables.F, using
+    standard order, except for:
+     DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
+     CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
 o new pkg: atm_phys
-  - add entry point for new pkg "atm_phys" (atmospheric physics pkg
-    from P. O'Gorman and T. Schneider, JCl, 2008).
+  - add entry point and source code (previously in contrib
+      verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
+    (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
   - re-order sequence of calls within packages_readparms.F,
      packages_init_fixed.F and packages_write_pickup.F
     (but skip packages_init_variables.F because of TAF issues).
+  - update contrib/*/atm_gray/ experiment.
 o pkg/seaice (ITD code):
   - simplify and fix the writing of pickup-files for ITD case
 o pkg/seaice (ITD code):
