CDO

Hello:

I tried to convert ICON data from unstructured to Lon/Lat grid like NCEP GFS as:

cdo -f grb2 -setgridtype,lonlat ICON_iko_single_level_elements_world_CLCT_MOD_2017111912_180.grib2 zzz

but always show the message below:

cdo setgridtype (Warning): Conversion of unstructured grid to regular grid failed!

cdo setgridtype (Abort): Unsupported grid type!

So appreciate if anyone have any comment for this issue.

Thanks,
Leon
