IR Satellite Pix Source?

[Richard A. Milewski]

Can anyone recommend a source for large-area infrared satellite images for
use with MapServer?

I'm currently using the images at http://aviationweather.gov/obs/sat/intl/,
but I would prefer larger images (higher pixel counts) and if possible
images without the political boundry overlays since I can plot those better
with MapServer.

I'm mostly interested in replacements for the ICAO area A, C, F, i, and M
maps.

Thanks!
