A 1-D radiative transfer study of mineral dust during CHARMEX/ADRIMED 2013 campaign

Abstract

A 1-D radiative transfer study is presented based on the measurements performed at Granada during a dust event within the framework of the ChArMEx/ADRIMED (Chemistry-Aerosol Mediterranean Experiment/Aerosol Direct Radiative Forcing on the Mediterranean Climate) campaign, during June 16-17, 2013. Ground-based AERONET and lidar measurements were performed and further processed with the GRASP algorithm to get spectrally-resolved profiles of extinction and single scattering albedo. Furthermore, the research aircraft ATR-42 made two flights above Granada providing vertical profiles of aerosol optical and microphysical properties together with measurements of broadband radiative fluxes. All of the ground-based and aircraft aerosol properties are used as input in the radiative transfer model GAME in order to evaluate its sensitivity to different input datasets. The aircraft fluxes are used for validation of the modelled ones.
