SYNAER
Please notice, ENVISAT instruments are currently not sending any data. Check the ESA ENVISAT page for latest news.
ENVISAT daily aerosol parameters (particle mass concentrations, optical depth and type) on a 60x30 km2 resolution are provided in near-real time (approximately 12 hours after acquisition) and as archive for 2003-2008 over Europe and Africa. These results are retrieved from a synergetic exploitation of two sensors onboard ENVISAT, the spectrometer SCIAMACHY and the radiometer AATSR. Due to the scan mode and swath width of the instruments full cloud-free coverage at the equator is achieved after 12 days.
