Organic aerosols (OA) affect climate forcing and human health, but still large uncertainties exist in their sources and evolution. A large fraction of submicron particulate matter, 20%90%, can be attributed to OA. Recent studies have shown that secondary organic aerosols (SOA) account for a large fraction of the OA burden. Most OA efficiently scatter visible radiation and...

Atmospheric particulate matter reduces visibility, adversely affects human health and impacts Earth's climate. Recent laboratory research has identified NH3 as a potentially important reactive species in the formation and aging of SOA, a significant but not-well-quantified class of aerosol particles. The goal of this project is to answer the questions: How does NH3 affect...

The main objective of this project (MDRAF) was to describe the 3D structure of Mediterranean desert dust outbreaks and study their effects on radiation and atmospheric dynamics by means of numerical modeling (NMMB/BSC Chemical Transport model-NMMB/BSC-CTM). Moreover, the meteorological feedbacks and the forecasting accuracy of NMMB/BSCCTM when dust effects are considered were...
