Re: how to mask the sea and interpolate the missing gap in land which has the same missing assignment with the sea?

NCL does not have a specific function for interpolating
classification data.

---
Interpolation of *classification* data (eg, 'land cover')
is non-trivial. Numbers are arbitrary. EG: 17 may be
tropical forest while 18 refers to desert. Typically people
use a nearest neighbor algorithm. However, nearby grid points,
separated by a narrow mountain range, may have completely different
land types.
