The idea being that there could be, simply, linear interpolation outside of the current interpolation boundary, which appears to be the convex hull of the data we are interpolating from. All these interpolation methods rely on triangulation of the data using the QHull library wrapped in scipy.spatial. Interpolation can be done in a variety of methods, including: 1-D Interpolation Spline Interpolation Univariate Spline Interpolation Interpolation with RBF Multivariate Interpolation Interpolation in SciPy Data point coordinates.

I can't check the code without having the data, but I suspect that the problem is that you are using the default fill_value=nan as a griddata argument, so if you have gridded points that extend beyond the space of the (x,y) points, there are NaNs in the grid, which mlab may not be able to handle (matplotlib doesn't easily). How can I perform two-dimensional interpolation using scipy? I am quite new to netcdf field and don't really know what can be the issue here.
