LISTOS Data Release Announcement

Project: LISTOS

The Atmospheric Science Data Center (ASDC) at NASA Langley Research Center has released data for the Long Island Sound Tropospheric Ozone Study (LISTOS). LISTOS was a field campaign that was conducted from June through September 2018. LISTOS explored high levels of ozone in the New York City metropolitan area with a focus on pollution transported over the Long Island Sound. LISTOS was a multi-agency collaboration involving NASA, NOAA, the United States Environmental Protection Agency, the Northeast States for Coordinated Air Use Management (NESCAUM) coalition, multiple local state agencies, and various other research institutions.

The high amounts of ground-level ozone in the New York City metropolitan area surpass federal standards and pose a significant problem for the air quality of the region and beyond.  The Long Island Sound has a unique geographical layout which confines pollutants to a marine boundary layer which are then carried inland by sea breezes. Thus, the Long Island Sound plays a key role in the transportation of pollution from the New York City metropolitan area inland to areas including Connecticut, Rhode Island, and Massachusetts. LISTOS explored the chemistry and dynamic patterns of the Long Island Sound to improve the understanding of pollution transportation in the region.

The NASA HU-25 aircraft, the University of Maryland Cessna 402B aircraft, and the Stony Brook University Long-EZ aircraft were equipped with in-situ and remote sensing instrumentation. A network of ground-sites, a mobile vehicle, and a ship were also used to collect LISTOS data. LISTOS provided an opportunity to prepare for future observations from the Tropospheric Emissions: Monitoring of Pollution (TEMPO) satellite by testing air quality remote sensing retrievals using the GEO-CAPE, GCAS, and GeoTASO airborne simulators. Additionally, LISTOS provided the opportunity to use airborne and ground-based measurements to validate Tropospheric Monitoring Instrument (TROPOMI) science products.

Data products are archived at the ASDC.
