AB: OH, HO2 and OH reactivity were measured from August 16 to Sep 27, 2006 on the top of Moody Tower at the University of Houston in Houston Texas. The site is located a few kilometers south of downtown Houston and a few kilometers west of the Houston Ship Channel, one of the busiest sea ports in United States. Diurnal variations of measured OH, HO2, and OH reactivity are presented. To further understand the photochemistry in the Houston city, measured OH and HO2 are compared to a chemical box model calculation. Measured OH reactivity is also compared to the calculated OH reactivity based on all available VOC measurements and other inorganic species.
