    "description": "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.\nThe data from each cruise is divided into multiple csv datasets, summarized as follows:\nMain - Navigation, Meteorology, Scattering, and Absorption;\nChemistry - Aerosol species concentrations at varying particle diameters;\nAOD - Aerosol optical depth at varying wavelengths;\nDMS - Seawater Dimethyl sulfide;\nRadon - Radon Concentration;\nSize Distribution (APS) - Aerodynamic Particle Size Distribution;\nSize Distribution (DMPS) - Differential Mobility Particle Size Distribution;\nSize Distribution - Merged version of the APS and DMPS datasets",
