Interpolate/extrapolate variables over land

Added by José Veiga about 10 years ago

Dear all,

in attach follows a figure showing a geopotential field over the globe. Note that over land there is no defined values. However I need values over the land. Thus, is there a function in CDO that interpolate (or extrapolate) variables to produce a field with continuos values over all domain and levels?

I really appreciate if some one could help me with this.

Kind regards,

José Augusto

The undocumented CDO operator fillmiss fills missing values by a bilinear interpolation of the next east/west/north/south value.

Dear Uwe Schulzweida,

It worked! Thank you very much. I tried:

cdo fillmiss orig_file.grb final_file.grb

Kind regards,
