New England Air Quality Study (NEAQS): Physical, optical, and chemical properties of atmospheric marine aerosols aboard NOAA R/V Ronald H. Brown in the Gulf of Maine and the northwest Atlantic, 2002-07-12 to 2002-08-10 and 2004-07-05 to 2004-08-13 (NCEI Accession 0311433)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 05:16 AM | Dataset Last Updated: January 13, 2026 at 12:00 AM
This dataset contains physical, optical, and chemical properties of atmospheric marine aerosols from two different cruises aboard NOAA R/V Ronald H. Brown as part of the NEAQS project. The first cruise (NEAQS-2002) took place from 12 July to 10 August 2002, and the second cruise (NEAQS-2004) from 05 July to 13 August 2004. 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; 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
