Are you using lat/lon as X/Y for griddata? Or are you projecting it first? You should project. Not seeing your code or data, I'm not sure I can diagnose what is going wrong with the interpolation.

I have been trying to follow your suggestion of projecting first.. see example later, but I'm not sure if I am doing it correctly. One question is how then would I return the interpolated array back to a lat/lon grid... it seems transform_scalar is set up to go from lat/lon TO projection. I guess it could be used to 'unproject' the data as well?
The output Z values will be in the same order as the inputs. There is nothing to do. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco
