POLDER
POLarization and Directionality of the Earth's Reflectances

The POLarization and Directionality of the Earth’s Reflectances (POLDER) is a spaceborne passive radiometer that was onboard the Japan Aerospace Exploration Agency’s Advanced Earth Observing Satellite. POLDER has also been utilized in several airborne investigations to perform instrument calibration and to provide measurements of surface reflectance and solar radiation. POLDER has a ground spatial resolution of 7 km x 6 km at nadir and operates across eight discrete spectral bands (443 nm - 910 nm).
