TRACER-AQ Data Release Announcement

July 21, 2022, 11:46 a.m.

The Atmospheric Science Data Center (ASDC) has released data for the TRacking Aerosol Convection ExpeRiment – Air Quality (TRACER-AQ) campaign. TRACER-AQ is a field study co-sponsored by NASA and the Texas Commission on Environmental Quality (TCEQ) with partners from the Department of Energy (DOE), TRacking Aerosol Convection ExpeRiment (TRACER), and several academic institutions. The campaign seeks to better understand photochemistry and meteorology that impacts the Houston, Texas, region, provide observations for evaluating air quality models and satellite observations, and to investigate the relationship between air quality and socioeconomic factors within Houston.

The primary observations for TRACER-AQ took place from mid-August to late September 2021. The campaign is supported by measurements from the NASA Gulfstream V aircraft carrying the GEOstationary Coastal and Air Pollution Events (GEO-CAPE) Airborne Spectrometer (GCAS) and the High Spectral Resolution Lidar-2 (HSRL-2). Ground-based measurements include those from ground-based lidars from the Tropospheric Ozone Lidar Network (TOLNet), ceilometers, Pandora spectrometers, AErosol RObotic NETwork (AERONET) remote sensors, ozonesondes, and stationary and mobile laboratories of in situ air quality and meteorological observations. TRACER-AQ 2 operations are planned for August through September 2022.

Additional information on TRACER-AQ can be found on the ASDC TRACER-AQ Landing Page.
