Remote marine environments, dominated by pristine atmospheric conditions of low aerosol concentrations, are the most impacted by perturbations in aerosol properties and represent one of the major constraints to accurate future climate predictions. With the objective of expanding the knowledge of aerosol properties and key processes in the marine environment, between 2015 and 2018, NASA deployed the North Atlantic Aerosols and Marine Ecosystems Study (NAAMES) field campaign in the Western North Atlantic region. 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). In this study, I integrate aerosol microphysical, optical, and chemical datasets collected during the NAAMES field campaigns to provide summary statistics of marine aerosol characteristics and aerosol budget over the Western North Atlantic Ocean region. In this presentation, I will 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.
