OK, so what do you mean by "displaced by 180 degrees"?
Do you mean that the lon vector, which goes from
-177.500 to 177.5 doesn't really describe where
the data is located? If you shifted your field
data in the x direction by 32, would the data look
correct on your map?

field = Shift(field, 36, 0)

Cheers,

David
