Re: [help] how to interpolate vector quantity with missing values

NCL has an Example Application page:
    http://www.ncl.ucar.edu/Applications/grid_fill.shtml

Note: NCL does not have a specific function for what you need
but you could try poisson_grid_fill on the gaussina
gridded data and then interpolate that to the new gid
