Branch: MAIN
CVS Tags: branch-exfmods-tag, checkpoint47e_post, checkpoint47, checkpoint47c_post, checkpoint47d_post, checkpoint47a_post, checkpoint46n_post, checkpoint47b_post, checkpoint47d_pre
Branch point for: branch-exfmods-curt
Changes since 1.2: +6 -26 lines
Merging from release1_p8:
o exf:
  updated external forcing package
  - bug fixes carried over from ecco-branch
    (missing OBCS_OPTIONS.h in two routines)
  - enable easy to use "no forcing".
  - added exf I/O for atmospheric loading
  - added exf I/O for runoff data
  - transfered scaling between exf <-> MITgcm to exf namelist
  - removing old exfa stuff
