This link contains NOAA satellite ATP data. It's FM modulated so you have to design FM demodulator and store the result as .wav file. Once you got the .wav file, use wxtoImg software for decoding .wav file into images.
If you want to capture data file by urself, use Cross dipole or QHF antenna.
I wrote about NOAA satellite receiver system and also included many other links related to NOAA in my blog http://amritasenthil.wordpress.com/
