[gradsusr] maskout with basemap

[Andrew Friedman]

Hi Jason,
I believe you can do what you are describing using maskout with a landmask that has the same dimensions as your dataset. You’ll need to either find an existing mask, or create one. If the mask isn’t the right dimension size, you may need to regrid it using the GrADS function lterp.
