Abstract

Reflection of solar radiation by tropical low level clouds has an important cooling effect on climate and leads to decreases in surface temperatures. Still, the effect of pollution on ubiquitous tropical continental low-level clouds and the investigation of the related impact on atmospheric cooling rates are poorly constrained by in-situ observations and modelling, in particular during the West African summer monsoon season. Here, we present comprehensive in situ measurements of microphysical properties of low-level clouds over tropical West Africa, measured with the DLR aircraft Falcon 20 during the DACCIWA (Dynamics Aerosol Chemistry Cloud Interactions in West Africa) campaign in June and July 2016.
