Cloud Reflectivity and Autoconversion Rate: Sensitivity to Organic Compounds for Different Aerosol Types

Abstract:

A number of aerosol particles released by human activities has the potential to cool the climate system by modifying the cloud radiative properties via the cloud formation process. Although the aerosols are mostly composed of inorganic species, measurements show organic compounds (OC) could also contribute to cloud condensation nuclei concentration and this depends on aerosol type. Our approach involves estimations of the cloud properties and autoconversion rate taking into account measured aerosol number size distributions and current observations of chemical composition for three types of aerosols: marine, rural, urban. We provide a measure of the ability of organics to change these parameters by calculating relative differences in cloud albedo and autoconversion rate when OC is included with respect to the case when only inorganic aerosol species are considered. The presence of organic compounds may enhance the cloud reflectivity by 1-5% and autoconversion rate changes with 2 orders of magnitude when we move from marine to polluted urban case, with respect to the base-case cloud droplet number. Keywords: aerosol physical and chemical properties, organic aerosol, cloud albedo, autoconversion rate
