CFSV2-LETKF

Strongly Coupled LETKF applied to the Climate Forecast System version 2 (CFSv2). Default settings use the T62/L64 version of GFS and the 0.5 degree MOM. Fix files, and CFSR data must be obtained separately. Information about how to run most of the scripts can be shown by running with the -h flag, (e.g. ./util/get_cfsr -h

All further documentation, including how to compile and run, are contained on the wiki: GitHub wiki for CFSv2-LETKF
