Description:

The southeast Atlantic hosts one of the largest subtropical stratocumulus decks on the globe along with the presence of spatially extensive shortwave-absorbing aerosols originating from biomass burning on continental Africa. From 2016 to 2018, several field experiments examined this unique aerosol–cloud system, motivated by common interests in articulating the direct, semidirect, and indirect radiative effects; improving their representation in global models; and understanding the relevant underlying processes. These recent campaigns include: NASA ORACLES (ObseRvations of Aerosols above CLouds and their intEractionS), DOE LASIC (Layered Atlantic Interactions with Clouds), the UK-led CLARIFY (Clouds and Aerosol Radiative Impacts and Forcing: Year 2017), the French-led AEROCLO-Sa (Aerosol Radiation and Clouds in southern Africa), and the German-led Namib Fog Life Cycle Analysis (NaFoLiCA). We invite a range of process-oriented and impact-oriented presentations based on these and other relevant aircraft, surface, and/or satellite-based datasets (e.g., A-Train, Meteosat Second Generation, AERONET, ATom) and relevant modeling studies over the African biomass burning region.
