SCIAMACHY/AATSR SYNAER
 |
 |
ENVISAT daily aerosol parameters (particle mass concentrations, optical depth and type) on a 60x30 km2 resolution are provided 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.
