The “setgrid”-operator can also be used to Learn how to use cdo_genbil and cdo_remapbil modules for a bilinear remapping of fields between grids in spherical coordinates. I somehow have the impression that this is rather an NCO-command problem I'd be very grateful for any helpful hint! Thanks and with best regards, Iris.
