Dear Maciej, From the ppregrid help pages: Quote: For all transformations, the resolution of the target grid must not exceed twice that of the source grid in either longitudinal or latitudinal directions The restriction is in place as bilinear interpolation (the method used in ppregrid) is not an appropriate method in this situation. I suggest using the ppaggregate command instead. All the best, Simon |
