One comment:

mgrid() is designed to interpolate form unstructured data to a regular grid.

Given  that your data is, in fact, quite structured, I suspect you may 
get better results from a a custom-written interpolator -- simple 
bi-linear (or bspline) interpolation would be pretty easy to write, and 
may give you a cleaner result. You may even be able to grab code 
straight from scipy.interpolate, an apply it on the different portions 
of your grid separately.

HTH,
