CFSR Data

CFSR data is needed as initial conditions for ensembles, verification, and as boundary conditions (ozone, etc) for model runs using real observations. The atmosphere files can be downloaded as one of two resolutions, T126 and/or T382, before being converted to T62, T126, T190, T382, T574, T1148. The ocean initial conditions can be downloaded only as 0.5 degree resolution.

To download just the initial conditions for a single date at T62 for use in a nature run beginning at Jan 1, 2010 run:

./util/scripts/cfsr_get --start 2010010100 --atm
./util/scripts/cfsr_get --start 2010010100 --ocn
./util/scripts/cfsr_chgres --start 2010010100 --ares 62

The resulting files will be downloaded to ./DATA/CFSR

Run either of the scripts with the -h option to get more information and runtime options about the scripts.
