A consortium of researchers from universities, private industry, and federal laboratories is joining the Texas Natural Resource Conservation Commission (TNRCC) and local communities in planning a major photochemical oxidant and aerosol field study in the eastern half of Texas in the late summer of 2000.

While the Houston-Galveston area will be a focus of the study, significant work throughout the eastern half of the state is also planned. Resources for this program include a monitoring network for ozone and aerosols augmented by at least one highly instrumented super-site, a surface meteorology network including wind profilers, two aircraft carrying a comprehensive suite of chemical instruments, a third aircraft for remotely sensing ozone and aerosol vertical profiles, and a fourth for source region characterization.

The Texas 2000 field program is one in a series of oxidant/aerosol studies which the National Oceanic and Atmospheric Administration (NOAA), the Department of Energy, and a number of university scientists have cooperatively conducted under the umbrella of the Southern Oxidants Study (SOS) in affiliation with NARSTO. The location was selected because the eastern half of Texas includes major urban areas with significant ozone pollution problems and possible difficulties meeting new national particulate matter standards, and because of the unique chemical and meteorological features in this area that make it important from a scientific perspective.

The goal of the study is to provide a better understanding of the basic chemical, meteorological, and atmospheric transport processes that determine ozone and fine particle distributions, and to develop new scientific understanding that will assist policy-makers in devising optimal ozone and PM management strategies.
