problem with labels

[Subodh Kumar Saha]

Dear Arpita,

One possibility would be to use land-sea mask data. If you have binary
file of that, replace Ocean point values by a negative number and then
use it in the "maskout" function.

if 's' is the variable where sea points are negative and land points are
positive (e.g. -1 for all sea points and + 1 for all land points) then,

 d maskout( precipitation, s)

will show the precipitation over land only, other points will be treated
like undefined values.

Regards,
Subodh
