Climatic impact of Asian soot particles from an observational perspective
Aerosol radiative forcing is a hot topic in climate change discussions and is strongly dependent on vertical distributions of aerosol particles. The most important features for calculating the radiative forcing are aerosol number and size distribution, particle optical properties and chemical composition. We are working on vertical aerosol in situ measurements of the field campaign CARDEX (Cloud Aerosol Radiative Forcing Dynamics Experiment) at Maldives Climate Observatory in Hanimaadhoo (Maldive Islands). CARDEX took place in February and March 2012 during the dry monsoon season with arriving polluted air masses from the Asian continent. Aerosol profiles could be measured with various instruments loaded on lightweight unmanned aerial vehicles. We focus on profiles of aerosol optical properties as scattering, extinction and absorption to determine aerosol optical depth for example. Furthermore comparisons with remote sensing measurements as LIDAR and sun photometers are made. In this context the quantification of surface as well as vertically resolved carbonaceous aerosol is very important.
