Hi Mary,
I have attached the script. The data files uploaded to server.
The interpolation is for 6 time slices, as a test, while I actually need to
do it for much more (200+) files. Source grid is very fine (1km) and has a
size of 20x30 degree; destination grid is 40km resolution on a curvilinear
(WRF) grid.
I wonder if there is a fast method for the interpolation.
