Hey Jeff, It's somewhere between the two - the original satellite swath is converted to a regular 0.5 degree grid by truncating, binning, and averaging each point's lons and lats over the top of a 720 x 360 np.zeros array. the plotting still works fine for non ortho/ hemispherical projections, and I've no big problem with using global projections for the time being. Thanks for your help in the meantime anyway.
Cheers, Will.
