UV ABSORBING AND SCATTERING AEROSOL INDICES FROM SCIAMACHY: COMPARISON WITH FIRE COUNTS FROM (A)ATSR

By Marloes Penning De Vries and Thomas Wagner

Abstract

The Absorbing Aerosol Index (AAI) is a well-known measure of UV-absorbing aerosols. Important advantages of the method are that AAI can be retrieved in the presence of clouds, and that it is insensitive to surface type. Recently, a counterpart to the AAI was introduced: the Scattering Aerosol Index (SAI). The SAI is a measure of aerosols with a single scattering albedo larger than roughly 0.9. We present recent SAI and AAI results from SCIAMACHY, and show that a seasonal cycle can be observed not only for AAI, but also for SAI. We also show time series of monthly averaged Aerosol Indices in six selected regions. We compare these to cloud fractions (from the FRESCO+ algorithm) and to fire counts from (A)ATSR. AAI was found to correlate well with fire counts in three biomass burning regions, and characteristic seasonal dependences of both AAI and SAI were found for all six regions. 1
