GLDAS netcdf to GRIB: ERROR Spherical Harmonics Coefficients

Added by Prasanth Valayamkunnath about 7 years ago

Hello CDO family,

I'm trying to run HRLDAS-3.7.1 with GLDAS data. GLDAS 0.25 degree is available only in NetCDF format. I have converted NetCDF data to grib using GLDAS Vtable as

cdo -f grb setzaxis,myzaxis2m.dat -setltype,105 -chparam,-1,11 GLDAS.grb ./GRIB/temp.grb

cat myzaxis2m.dat

zaxistype = height
size = 1
levels = 2

I have checked the temp.grb file. It worked perfectly. However, when I input this data into HRLDAS it showed an error

STOP " Section 4: Spherical Harmonic coefficients".

How can I solve this issue?

I'm attaching grib_dump print output, grib file, and source NetCDF file.
Any would be greatly appreciated.

Thanks
Prasanth

Hi Prasanth,

I'm not familiar with GLDAS and HRLDAS but assuming that HRLDAS is a program you use to read the converted data file you should have a closer look at HRLDAS first. What does the message mean? Is there something missing in the GRIB file? Can HRLDAS read only GRIB files? We need to know more before we can help. Sorry.

Thanks, Karin. I have solved the issue. I don't know what was the exact problem. Maybe I was using an old version of CDO.
