Analysis of 5 years SCIAMACHY Absorbing Aerosol Index data

LG Tilstra, M de Graaf, I Aben, P Stammes

We study the quality of the SCIAMACHY Absorbing Aerosol Index (AAI) product developed at our institutes. The AAI in general is determined from the reflectance at two wavelengths in the UV, and is highly sensitive to errors in the absolute radiometric calibration. We apply a degradation correction to the level-1 reflectance and test the temporal behaviour of the resulting AAI data. This we do by studying time series of AAI data for a selection of areas on the globe. We conclude that the AAI data we provide is of good quality and is stable over the entire time range of SCIAMACHY data currently available.
