AB: The Particle-Into-Liquid Sampler (PILS) was deployed on NOAA's WP-3D aircraft during the summer of 2004 in support of the Intercontinental Transport and Chemical Transformation - New England Air Quality Study. Concurrently, the PILS was also deployed on NASA's DC-8 in as part of the Intercontinental Chemical Transport Experiment North America (INTEX-NA). Throughout the duration of the study, semi-continuous measurements of fine (PM1.0) inorganic ion components (sodium, ammonium, potassium, calcium, magnesium, chloride, nitrate, and sulfate) were made on both aircraft and water-soluble organic carbon on the NOAA WP-3D. The measurement domain was extensive, with spatial distribution encompassing Northern Quebec, the Azore Islands, the Gulf of Mexico, and the upper Midwest of the United States. Intensive sampling of the urbanized metropolitan areas of the Northeast (e.g. Boston-New York-Washington corridor), as well as biomass plume studies, were also conducted. Within this measurement domain, a range of aerosol sources were sampled, including fresh power plant plumes, relatively fresh and aged urban plumes, and aged biomass plumes. In this paper, we will present an overview of the measurements, compare the bulk chemical data to fine particle volumes, investigate spatial distributions, compare measurements to surface sites, and identify unique plumes encountered during the mission.
