    The Absorbing Aerosol Index (AAI) indicates the presence of elevated absorbing aerosols in the Earth's atmosphere. The aerosol types that are mostly seen in the AAI are desert dust, biomass burning and volcano ash aerosols. The AAIs provided here are derived from the reflectances measured by GOME-2 at 340 and 380 nm (from the Science Channels). The pictures below are updated every 15 minutes and present the most recent AAI measurements obtained from GOME-2 on MetOP-A from ACSAF data.

    Please note that there is sun glint (reflection from the sun on water surfaces to the satellite) and that this shows up as increased AAI values in the eastern one-third of the swath.
