Impact/Purpose:
The goal of this task is to thoroughly characterize the performance of the emissions, meteorological and chemical/transport modeling components of the Models-3 system, with an emphasis on the chemical/transport model, CMAQ. Emissions-based models are composed of highly complex scientific hypotheses concerning natural processes that can be evaluated through comparison with observations, but not validated. Both performance and diagnostic evaluation together with sensitivity analyses are needed to establish credibility and build confidence within the client and scientific community in the simulations results for policy and scientific applications. The characterization of the performance of Models-3/CMAQ is also a tool for the model developers to identify aspects of the modeling system that require further improvement.
Description:
During the late summer of 2000 (8/15 - 9/15/00), the Texas Air Quality Study - 2000 (TEXAQS-2000) was conducted to improve understanding of the factors that control the formation and transport of air pollutants along the Gulf Coast of southeastern Texas. An international team of scientists used a variety of real-time and 24-hour averaged instruments to characterize ambient aerosols at three specific sites. The three sites (LaPorte, HMR3, Aldine) where chosen to characterize the nearby petrochemical refineries that line the shipping channel between Galveston Bay and central Houston. The main focus will be the inter-site comparison of over 60 non-polar semi-volatile organic species collected with a high capacity Integrated Organic Gas and Particle (HiC IOGAP) sampler.
