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?

Thanks!
