Branch point for: release1_50yr
Changes since 1.1: +2 -2 lines
Merging changes on MAIN between checkpoint43 and checkpoint43a-release1mods
Command: cvs -q update -jcheckpoint43 -jcheckpoint43a-release1mods -d -P

These changes are most of the changes between c43 and c44 except those
that occured after "12:45 11 Jan 2002". As far as I can tell it is
checkpoint43 with the following mods:

  o fix bug in mom_vi_del2uv
  o select when filters are applied ; add options to zonal_filter (data.zonfilt)  o gmredi: fix Pb in the adiabatic form ; add options (.e.g. Bolus advection)
  o update AIM experiments (NCEP input files)
  o improve and extend diagnostics (Monitor, TimeAve with NonLin-FrSurf)
  o added some stuff for AD
  o Jamar wet-points

This update does not contain the following mods that are in checkpoint44

  o bug fix in pkg/generic_advdiff/
    - thread related bug, bi,bj arguments in vertical advection routines
  o some changes to pkg/autodiff, pkg/cost, pkg/exf, pkg/ecco,
    verification/carbon and model/src/ related to adjoint
  o some new Matlab scripts for diagnosing model density
    - utils/matlab/dens_poly3.m and ini_poly3.m

The list of exclusions is accurate based on a "cvs diff". The list of
inclusions is based on the record in doc/tag-index which may not be complete.
