Revision 1.1 - (show annotations) (download)
Thu Nov 18 04:00:04 2010 UTC (13 years, 6 months ago) by dimitri
Branch: MAIN
This is a first sketch of a bottom boundary layer parameterization
for MITgcm.  The hooks to main model currently reside with pkg/mypackage
and it is temporarily checked in MITgcm_contrib until it clears the
App Store vetting process.  Instructions on running a simple test
integration in a periodic channel are in MITgcm_contrib/bbl/readme.txt
and some output can be viewed using lookat_output.m in same directory.
