Lead Scientist: Peter Daum

Observatory: OSC

Over 250 scientists and technicians from over 40 organizations participated in TexAQS 2000, a major air quality study focused on Houston, Texas. The study was one of the largest, most comprehensive and sophisticated studies of urban air quality that has ever been conducted in the US. Resources for the program included five aircraft; major chemistry sites at Laporte airport adjacent to the Houston Ship Channel, and on the 62nd floor of Williams Tower on the west side of Houston; EPA-funded (U. of Texas GC-ARCH Program) aerosol/chemistry sites located up, in, and downwind wind of the Ship Channel, and; a well-developed ozone/aerosol monitoring network supported by TNRCC, the City of Houston, and a consortium of industries in the Houston area. Meteorological resources included five wind profilers, and three rawinsonde launch sites.
