ENVISAT

Envisat, a follow-on to ERS series, is the largest Earth Observation spacecraft ever built.

Onboard instruments relevant for oceanography include an Advanced Synthetic Aperture Radar (ASAR) providing measurement of sea surface (wind, wave spectra, roughness), a imaging spectrometer (MERIS) prodviding ocean color data and an Advanced Along Track Scanning Radiometer (AATSR) providing measurement of sea surface temperature (complementing the ATSR onboard ERS-1 and ERS-2).

ENVISAT at CERSAT The CERSAT processes and delivers AATSR data in the frame of MEDSPIRATION project, as well as regional ocean color products. It is also in charge of the reprocessing of the ASAR wave spectra data. Refer to data section.
