The Houston region commonly has isolated convection in the presence of variable aerosol environments with measurements strategically placed to capture urban, rural, and marine driven aerosol conditions. language code: en Date=2021-09-20 User Id=tstevens Entity=BroaderRelation Operation=INSERT User Note=Insert Concept System Note=add broader relation New Value=TRACER-AQ [4f9f5ca4-24c0-49a6-950f-991e0ee827bf,749511] - S - U [4eb1894b-35b4-406b-8864-944a42bc7702,743116] Date=2021-09-20 User Id=tstevens Entity=AltLabel Operation=INSERT System Note=insert AltLabel New Value=id: null category: primary text: Tracking Aerosol Convection ExpeRiment – Air Quality language code: en Date=2026-02-06 User Id=tstevens User Note=updated keyword definition The TRacking Aerosol Convection ExpeRiment – Air Quality (TRACER-AQ) campaign was a field study co-sponsored by NASA and the Texas Commission on Environmental Quality), with partner from the Department of Energy (DOE), TRacking Aerosol Convection ExpeRiment (TRACER), and several academic institutions. This synergistic effort aimed to gain an updated understanding in photochemistry and meterological impact on ozone formation in the Houston region, particularly around the Houston Ship Channel, Galveston Bay, and the Gulf of Mexico; and provide observations for evaluating air quality models and satellite observations. 2026-02-06T12:47:16.503Z
