Alternatives to cnvgrib for GRADS

[Brian Gaze]

I'm trying to use degrib. Everything 'works' ok and the files and the GrADS
datafiles are created, but the .ctl only contains one variable. This is
despite the fact that I have download the complete (~46mb) GRIB2 file.

The commands I'm running to convert are:

/degrib/bin/degrib "GRIB file" -C -msg 1 -Flt
/degrib/bin/degrib "GRIB file" -C -msg 1 -Flt -Interp -GrADS
/degrib/bin/degrib "GRIB file" -C -msg 1 -Flt -GrADS

The .ctl file created contains the following information showing only 1
variable instead of the full set which I would expect to see. Any ideas what
is causing this to happen?


DSET ^HGT_12061200.flt
OPTIONS big_endian
OPTIONS yrev
UNDEF 9999.000000
TITLE GrADS control file based on GRIB2 file.
XDEF 720 LINEAR 0.000000 0.500000
YDEF 361 LINEAR 90.000000 0.500000
ZDEF 1 LINEAR 0 1
TDEF 1 LINEAR 12:00Z02Dec2007 1MN
VARS 1
HGT 1 99 Geopotential height [gpm]
ENDVARS


Thanks

Brian
