Retrieval of aerosol properties from polarization measurements
Abstract
The Global Ozone Monitoring Experiment-2 (GOME-2) has been launched in October 2006. In addition to measuring the intensity in the UV, Visible and Near Infrared at medium to high spectral resolution, GOME-2 also measures the polarization of light in 15 spectral bands. The polarization measurements provide valuable information on aerosol microphysical- and optical properties. We present a retrieval algorithm for the retrieval of aerosol total amount, size distribution, refractive index, and the corresponding optical properties. The retrieval is based on online vector radiative transfer calculations and an analytical inversion approach. Hence, it is not restricted to a number of standard aerosol models. We will show first results for aerosol retrieval from GOME-2 and discuss the accuracy of the polarization measurements.
