VAMOS Ocean-Cloud-Atmosphere-Land Study - Regional Experiment (VOCALS-REx): Physical, optical, and chemical properties of atmospheric marine aerosols aboard NOAA R/V Ronald H. Brown in the tropical eastern Pacific, 2008-10-20 to 2008-12-01 (NCEI Accession 0310622)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: May 06, 2026 at 03:43 AM | Dataset Last Updated: December 16, 2025 at 12:00 AM
This dataset contains physical, optical, and chemical properties of atmospheric marine aerosols from NOAA Ship Ronald H. Brown, collected 20 October to 01 December 2008 during the VOCALs field campaign. The data is divided into eight csv datasets, summarized as follows: Main - Navigation, Meteorology, and Scattering; 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;
