This pages links to the observation of the satellites of following dates, that were optimal for the validation purposes:
- 13 June 2008 12:00-15:30
- 17/18 June 2008 22:15-01:45
- 22 June 2008 10:30-12:15
- 03 July 2008 10:00-12:00
The data sets are stored on the FTP site of ICARE and is available only for CREW members, see Data_Access.

AVHRR instruments measure the reflectance of the Earth in 5 relatively wide (by today's standards) spectral bands. The first two are centered around the red (0.6 micrometer, 0.5 THz) and near-infrared (0.9 micrometer, 0.3 THz) regions, the third one is located around 3.5 micrometer, and the last two sample the thermal radiation emitted by the planet, around 11 and 12 micrometers, respectively.
