replace missing data in one file with data from another file

Added by Oliver Angelil about 7 years ago

Attached are two files with the same grid (60 time x 96 lon x 73 lat).

Where "GHCND" has missing data, I want to fill it with data from "H2". I want to do this at each grid cell and time step. I will ideally end with a file of the same dimensions but fewer missing values. Can CDO do this?

Thanks.
