Can NCL do this? Yes, of course.

How NCL does this is up to you. It depends on what *you* want.
Also, it depends upon the form of the mask. EG

      [a] Is it a simple 0-land, 1-ocean mask?
      [b] Is the mask a 0-land, 1-island, 2-inland-sea, ...,(N-1)-ice N-ocean

[1] Do u want the mask to be point specific?

    In this case, a simple nearest neighbor algorithm can be used.

[2] In some cases, an areal average of the points is appropriate.

Also, NCL has a function which can be used
to generate a mask.
