Re: divergence - missing values

NCL contains no functions that will compute divergent wind components
from an containing with missing values.

Is the grid global or a regional?

If global, you could possibly use 'poisson_grid_fill' to fill in the
missing data; then use the spherical harmonic functions
see: http://www.ncl.ucar.edu/Applications/wind.shtml

Then mask out the original missing grid points.

This will be 'good-enough' for most applications.
