Western Atlantic Climate Study (WACS): Physical, optical, and chemical properties of atmospheric marine aerosols in Georges Bank and the Sargasso Sea aboard NOAA R/V Ronald H. Brown (2012-08-19 to 2012-08-28) and WHOI R/V Knorr (2014-05-20 to 2014-06-06) (NCEI Accession 0310824)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 05:15 AM | Dataset Last Updated: January 06, 2026 at 12:00 AM
This dataset contains physical, optical, and chemical properties of atmospheric marine aerosols from two different cruises as part of the WACS project. The first cruise (WACS) was aboard NOAA R/V Ronald H. Brown from 19 August to 28 August 2012. The second cruise (WACS-2) was aboard WHOI R/V Knorr from 20 May to 06 June 2014. The data from each cruise is divided into multiple 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; DMS - Seawater Dimethyl sulfide; 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
