Hi, Carolina:

To use GFS11 data, because it's GRIB format, and RegCM doesnot support GRIB
format, as a first step, you have to convert the required fields (U, V, T,
Q, etc) into
a direct-access binary format. The original  fnl_20110601_00_00_c doesn't
work.

Usually, I use wgrib to do this step. Since the present RegCM4.1.1 prefer
netCDF
input/output, I think the interface of GFS11 should be modified and
improved.

Regards,
Xunqiang Bi
