[ncl-talk] Is there any functons to extract the grid data in a irregular area

[Adam Phillips]

Hello,
Shapefiles would be one way to mask your data. There are numerous shapefile
examples, but example 21 uses WRF data to mask a shapefile region:

Hope that helps. If not, or if you have further queries please respond to
the ncl-talk email list.
