cdo process the gx1v7 cmip6 CESM2 historical run sea ice with remapbil command

Added by xigua and summer about 5 years ago

Dear sir
I download the gx1v7 cmip6 CESM2 historical run sea ice from the site https://esgf-node.llnl.gov/search/cmip6/. then I use the remapbil command to transform the gx1v7 grid to the r360x180 grid with the 1.6.6 version cdo. the command and result shown here：

cdo remapbil,r360x180 siconc_SImon_CESM2_historical_r1i1p1f1_gn_185001-201412.nc remapbil.nc
Warning (cdfScanVarAttributes) : NetCDF: Variable not found - areacello
cdo remapbil: SCRIP bilinear remapping from curvilinear (320x384) to lonlat (360x180) grid, with source mask (86096)
cdo remapbil: Processed 243302400 values from 1 variable over 1980 timesteps ( 81.29s )

This warning lead to the figure of remapbil.nc different to the figure of siconc_SImon_CESM2_historical_r1i1p1f1_gn_185001-201412.nc at every timesteps.

I don't know how to correct this data conversion error. Any suggestion is worth learning. Thanks the help from the cdo
