The KNMI scientific Absorbing Aerosol Index (AAI) product from SCIAMACHY is presented. It is compared to the operational SCIAMACHY level-2 AAI product and to the TOMS AAI on the basis of a recent dust outbreak on 5 April 2004 over the Sahara. The scientific AAI product is still very sensitive to calibration errors in the reflectance, but its values are in the right range compared to TOMS AAI and it produces physically meaningful results.
