FIREX-AQ ER-2 In-Situ Meteorological and Navigational Data

FIREXAQ_MetNav_AircraftInSitu_ER2_Data_1 are meteorological and navigational data collected onboard the Earth Resources-2 (ER-2) aircraft during the Fire Influence on Regional to Global Environments Experiment - Air Quality (FIREX-AQ) Campaign. Completed during summer 2019, FIREX-AQ used a combination of instrumented airplanes, satellites, and ground-based instrumentation. Specifically, data was collected by the NASA Airborne Science Data Telemetry (NASDAT) System on the ER-2 platform. Data collection for this product is complete. Detailed fire plume sampling was carried out by the NASA DC-8 aircraft, which had a comprehensive instrument payload capable of measuring over 200 trace gas species, as well as aerosol microphysical, optical, and chemical properties. The DC-8 aircraft completed 23 science flights, including 15 flights from Boise, Idaho and 8 flights from Salina, Kansas. NASA’s ER-2 completed 11 flights, partially in support of the FIREX-AQ effort. The ER-2 payload was made up of 8 satellite analog instruments and provided critical fire information, including fire temperature, fire plume heights, and vegetation/soil albedo information. A ground-based mobile lab provided in-situ measurements of aerosol microphysical and optical properties, aerosol chemical compositions, and trace gas species. The FIREX-AQ campaign was a NOAA/NASA interagency intensive study of North American fires to gain an understanding on the integrated impact of the fire emissions on the tropospheric chemistry and composition and to assess the satellite’s capability for detecting fires and estimating fire emissions. The overarching goal of FIREX-AQ was to provide measurements of trace gas and aerosol emissions for wildfires and prescribed fires in great detail, relate them to fuel and fire conditions at the point of emission, characterize the conditions relating to plume rise, and follow plumes downwind to understand chemical transformation and air quality impacts.
