A study of the semi-direct and indirect aerosol effects on the Arctic region during the ISDAC campaign using WRF-CHEM

The Arctic region plays a very important role in our weather and climate system. However, numerical modeling of the weather and climate system in this region is a highly complex scientific problem and not well understood. In this study, the understanding of aerosol effects on clouds and the surface energy budget in the Arctic region has been improved by integrating observational analyses from the ISDAC field campaign (April 2008) and numerical simulations from the WRF-CHEM mesoscale meteorological model.
