Abstract
Beginning in August 2021 for 14 months, a multi-agency succession of field campaigns will take place in the coastal, urban regime of Houston, TX to study the interactions among clouds, aerosols, pollutants and the environment. A major component of these campaigns is the measurement of aerosol properties to better understand their lifecycle and influences on clouds and air quality.
The DOE TRacking Aerosol Convection interactions ExpeRiment (TRACER; October 2021 - September 2022) includes the deployment of the ARM Mobile Facility (AMF1) near the polluted Houston ship channel. The AMF1 includes the Aerosol Observing System providing continuous, surface-based measurements of aerosol and trace gases. During summer 2022, additional aerosol measurements will be made in a cleaner region southwest of Houston, and mobile and tethered balloon system platforms will capture aerosol regional variability.
TRACER-Air Quality (NASA and TCEQ; September 2021), brings a network of ground-based remote-sensing observations of ozone and other pollutants, balloon-borne measurements and remote-sensing aircraft measurements. The measurements will be used to address questions related to pollution, influences of photochemistry and local meteorology, the evaluation of air quality models and satellite products, and the intersection of air quality and socioeconomic factors.
The NSF Experiment of Sea Breeze Convection, Aerosols, Precipitation and Environment (ESCAPE) campaign will take place from mid-June through mid-July 2022 and brings an array of aircraft, and surface-based fixed and mobile measurements. Specific to aerosol studies, the ESCAPE aircraft will measure aerosol and ice nucleating particle concentrations.
These campaigns bring together a diverse cross-section of scientists, employing an array of surface-, aircraft- and satellite-based measurements, combined with state-of-the-art Earth system modeling to answer fundamental questions important for our understanding of weather, climate and air quality that would not be possible without these cooperative efforts.
