ARM Cloud Aerosol Precipitation Experiment (ACAPEX): Aerosols and Ocean Science Expedition (AEROSE)

Observatory: AMF, ACX

The NOAA Aerosols and Ocean Science Expeditions (AEROSE) constitute a comprehensive measurement-based approach for gaining understanding of the impacts of long-range transport of aerosols over the tropical ocean (Morris et al., 2006; Nalli et al., 2011). The AEROSE campaigns (to date, comprised of 9 separate trans-Atlantic Project legs) have thus provided a set of in situ measurements to characterize the impacts and microphysical evolution of continental aerosol outflows (including both dust and smoke) across the Atlantic Ocean (Nalli et al., 2011). AEROSE has sought to address three central scientific questions (Morris et al., 2006): 1. How do aerosols (e.g., dust, smoke) affect atmospheric and oceanographic parameters during marine transport? 2. How do the aerosol distributions evolve physically and chemically during transport? 3. What are the capabilities of satellite remote sensing for resolving and studying the above processes? (i.e., Satellite Cal/Val) We have recently added a fourth study focused on the transport and evolution of microbial communities on atmospheric particulate in the marine boundary layer.
