I have some ECMWF grib files where the data is stored as spherical
harmonics. Does anyone have idl code to convert the coefficients to
gridded (lat/lon) data? Alternatively, do you have other programs to
dump the data from the grib file, convert the spherical harmonics, and
write it out? (I know there is a lot of stuff out there to handle
grib files [ncl_convert2nc, wgrib, emos, PyNIO, ..] but I need someone
with real experience to sort it out.

Cheers,
