Atlantic Tradewind Ocean-Atmosphere Mesoscale Interaction Campaign (ATOMIC): Physical, optical, and chemical properties of atmospheric marine aerosols aboard NOAA R/V Ronald H. Brown in the tropical North Atlantic, 2020-01-07 to 2020-02-11 (NCEI Accession 0311369)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: May 06, 2026 at 03:44 AM | Dataset Last Updated: January 08, 2026 at 12:00 AM
This dataset contains physical, optical, and chemical properties of atmospheric marine aerosols from aboard NOAA R/V Ronald H. Brown, collected 07 January to 11 February 2020 during the ATOMIC field campaign. The data is divided into eight csv datasets, summarized as follows: Main - Navigation, Meteorology, Scattering, and Absorption; Chemistry - Aerosol species concentrations at varying particle diameters; AOD - Aerosol optical depth at varying wavelengths; Radon - Radon Concentration; CCN - Cloud Condensation Nuclei; Size Distribution (APS) - Aerodynamic Particle Size Distribution; Size Distribution (DMPS) - Differential Mobility Particle Size Distribution; Size Distribution - Merged version of the APS and DMPS datasets
