Fabozu,

I'm currently investigating pollution trends (namely NO2) over large
areas using data from the OMI (AURA) instrument. The pixels at nadir
have a size of 13 x 24 km, but I want to regrid those to a much higher
resolution. I would ideally like an uninterrupted dataset without
missing pixels so I can do a Fourier analysis around certain latitude
bands, which is why I'm looking to interpolate them in the first
place.
