Abstract
In this study, we provide summary statistics of marine aerosol characteristics and aerosol budget over the Western North Atlantic ocean region, collected during the North Atlantic Aerosols and Marine Ecosystems Study (NAAMES). Remote marine environments, dominated by pristine atmospheric conditions of low aerosol concentrations, are the most impacted by perturbations in aerosol properties and the major constraint to accurate future climate predictions. In this context, between 2015 and 2018, NASA deployed the NAAMES filed campaign with the objective of expanding the knowledge of aerosol properties and key processes in the marine environment. In situ ship- and aircraft-based measurements and airborne-based remote sensing retrievals were coupled during three field campaigns: NAAMES-1 (November 2015), NAAMES-2 (May 2016), and NAAMES-3 (September 2017). Here, we integrate aerosol microphysical, optical, and chemical datasets from the three platforms, and we discuss the spatiotemporal variability of aerosol and aerosol key processes in function of different aerosol loadings and meteorological regimes. Preliminary analysis of the consistency between in situ and remote sensing aerosol observations will also be assessed.
