CDO

Greetings,

I recently downloaded MPI-ESM1-2-LR data from the cmip6 historical run at the Copernicus Climate Data Store. The data was supposed to include data at all longitudes and from 20S to 20N.

I have not bee able to use this data due to the irregular grid and haven't been able to figure out how to use cdo to help.

FIRST example:
silvers$ cdo remapbil,r360x40 tos_Omon_MPI-ESM1-2-LR_historical_2tsteps.nc output.nc

cdo remapbil (Abort): Unsupported generic coordinates (Variable: tos)!

SECOND example:
silvers$ cdo -O sellonlatbox,-100,0,5,15 -setgridtype,unstructured tos_Omon_MPI-ESM1-2-LR_historical_2tsteps.nc tmp.nc
cdo(1) setgridtype: Process started

cdo sellonlatbox (Abort): Cell center coordinates missing!

Can you please help me understand how to use cdo with this grid? Thank you in advance.

for reference, I am including below the info from an ncdump command on the tos_Omon_MPI-ESM1-2-LR_historical_2tsteps.nc
