Timeline

POLarization and Directionality of the Earth's Reflectances

The French space agency, CNES, has developed the POLDER instrument, which flew on ADEOS (ADvanced Earth Observation Satellite), developed by the Japanese space agency, JAXA. This was the first French/Japanese cooperative project in the area of Earth observation.

A second, identical instrument flew on ADEOS-2, successor to ADEOS, until October 2003.

POLDER is a wide field of view imaging radiometer that has provided the first global, systematic measurements of spectral, directional and polarized characteristics of the solar radiation reflected by the Earth/atmosphere system. Its original observation capabilities have opened up new perspectives for discriminating the radiation scattered in the atmosphere from the radiation actually reflected by the surface.
