     Notes on tags used in MITgcmUV
     ==============================
 
+o pkg/generic_advdiff:
+  Change OBCS in multiDim advection (gad_advection.F):
+   Use maskInC to prevent intermediate update of tracer-field in OB regions,
+   thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
+   which were applying future time-step OB values.
+  This way, all explicit calculations use current-time-step OB values
+   (simpler and more consistent).
+  Affects results when set-up uses time-varying OBC and multi-dim advection;
+   update output of experiment seaice_obcs.
+o pkg/seaice:
+  move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
+   this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
+     SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
+  Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
+   but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
+   unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
+  For OBCS, close southern and western boundaries for sea ice solver
+   based on myYGlobalLo and myXGlobalLo instead of OB_Js and OB_Iw.
+o pkg aim (2010/10/26):
+  - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
+    formulation with obliquity, eccentricity, ... as run-time parameters,
+  - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
+    upward shortwave radition at the surface (all-sky and clear-sky).
+o pkg/obcs:
+  - writing sections with globalFiles=T does not work: switch to tiled-files
+    when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
+  - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
+  - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
+
+checkpoint62m (2010/10/21)
+o pkg/seaice: vectorize seaice_solve4temp.F
+  - move iterations loops outside of i/j-loops
+  - requires 2D arrays for TB and effConduct
+  - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
+    modified in this routine
+  - a little bit of clean up, adjusting indentation, etc.
+  - replaced a few TEN**a by exp(a*log(10.)) in new code for better
+    performance and '**TWO' by '**2' (because TWO is a float),
+    replaced ONE, ZERO
