Hi Klemen, sorry for delayed response - been away last week. Thanks
very much for your suggestion. I did try removing the data at 90
degree latitude, but it still doesn't work. It is just so weird that
the same code works only on my first set of data which is a bit larger
than the second set. Perhaps I should try regular interpolation as
suggested by Yngvar below.

Jenny
