Mobile Laboratory Measurements of Ozone, NO2, and Submicron PM During the 2018 LISTOS Field Intensive
Abstract
The Long Island Sound Tropospheric Ozone Study (LISTOS) is a multi-organization collaborative study focusing on the Long Island Sound and surrounding coastlines that continue to suffer from poor air quality exacerbated by land/water circulations. The ASRC Mobile Laboratory participated in the 2018 summer intensive measurement project by making on road and targeted deployments across Long Island and into the northern suburbs of New York City including western Connecticut. Instrumentation in the Dodge Sprinter van mobile laboratory for these deployments included a UV absorption O3 monitor, a CAPS NO2 monitor, a pDR1500 optical scattering PM monitor, an Aerodyne HR-ToF-AMS, and a passive canister sampler for collecting whole-air samples for off line analysis of VOCs. Numerous deployments of this platform were made starting from the Flax Pond Marine Laboratory in Old Field, NY on the north shore of Long Island. The measurements show remarkably sharp gradients in O3, NO2, and Ox (= O3 + NO2), reflective of a very photochemically active and meteorologically complex environment. Additional measurements and analyses will be discussed as part of this presentation.
