Hi Neil,

Try:

opt@SrcMask2D = where(.not.ismissing(datS),1,0)

This provides a mask array where you don't want the regridding to occur.

This _FillValue assignment seems to work when reading the source data, but not during the interpolation. For example when I interpolate Temperature data, I receive the below output.
