The coastal urban environment presents unique challenges to our understanding of cloud, precipitation, and aerosol processes, regional air quality, local meteorological circulations, and the interactions among them. To better understand these processes and improve their representation in Earth system models, a multi-agency set of field campaigns are collecting a comprehensive set of state-of-the-art measurements in the Houston, Texas, region from September 2021 through September 2022. Meet some of the scientists involved in these studies and learn about their research at a Town Hall during the American Geophysical Union 2021 fall meeting.
WHAT: Hybrid in-person/online Town Hall event at the AGU 2021 fall meeting
WHEN: Monday, December 13, 2021, 11:15 a.m. – 12:15 p.m. U.S. Central Time (12:15 – 1:15 p.m. Eastern Time)
WHERE: In-person: New Orleans Ernest N. Morial Convention Center, 900 Convention Center Blvd, New Orleans, LA 70130 - Room 346-347 Online: Link will be available to registered reporters.
REGISTRATION REQUIRED: Press registration is free; up to five days required for verifying credentials
DETAILS: Houston, Texas, lies within a humid subtropical climate regime where onshore flow and copious sea-breeze-driven convection interacts with local urban and industrial emissions to degrade air quality. Multiple agencies (the U.S. Department of Energy, the National Science Foundation, NASA, and the Texas Commission on Environmental Quality — or TCEQ) have converged on the area to study these interactions. DOE’s TRacking Aerosol Convection interactions ExpeRiment (TRACER) focuses on aerosols (natural and industrial) and cloud lifecycle, and aerosol-convection interactions. NSF’s Experiment of Sea Breeze Convection, Aerosols, Precipitation and Environment (ESCAPE) campaign addresses the influences of the sea breeze and urban environment on convective clouds. And the NASA TRACER-Air Quality (AQ) campaign investigates the environmental influences on regional air quality. This Town Hall meeting will introduce each campaign, discuss some of the first observations, provide perspectives on the interagency cooperation, and offer opportunities for the science community to engage with follow-on research activities.
