Urban atmospheric chemistry is driven by radical species which participate in various chemical reaction cycles that ultimately lead to the formation of ozone and particulates. An accurate quantitative description of radical chemistry, as well as the chemistry and sources of the various radical precursors, is essential to an understanding of air quality in Houston, and measurement of formaldehyde, in particular, is important to understanding the radical budget in Houston. Sources of HCHO include direct emission from vehicles, potential emissions from flaring at petrochemical facilities, and its photochemical production from the oxidation of numerous VOC species such as ethene and propene. Understanding the sources and spatial and temporal variability of HCHO is important for photochemical modeling of ozone in the Houston airshed and related SIP plan development. This project directly addresses sections 1.3, 4.2, and 6.2 of the TERC-SRP, which calls for a better determination of the HCHO emission fluxes in Houston. This project will be performed in close collaboration with the UCLA group led by Dr. Jochen Stutz; in fact, the UCLA and WSU instruments will need to work together cohesively to meet campaign objectives. Data and results will be made available to all collaborators, TERC, and TCEQ.
