Remapbil worked and they are on the same horizontal grid now. I tried to do the regrid but it did not work. where infile1 is the target grid you want to map to and infile2 is the data you want to regrid. cdo remapbil (Abort): Unsupported grid type: generic. I don't know why the output is nan. nc before the computation, it does not throw an error, but the task does not complete and freezes the terminal. cdo remapbil from polar_stereographic to lonlat grid, lon » seaice_conc_daily_nh_19810101_n07_v04r00. 79911 by 0. 00s 22MB] or you can take a look at the lat/lon values with ncdump. bs uz us tb dt zz bk ge pl ul
