is the variable you are regridding? If so, then you will need to make sure the lat/lon arrays are set to the same lat/lon arrays as "var". In fact, since "var" is a rectilinear grid and has lat/lon attached as coordinate arrays, you shouldn't need to set
SrcGridLat or SrcGridLon at all.<o:p></o:p></span></p>
