AB: We use airborne lidar and in situ measurements of ozone collected during the TexAQS 2000 and TexAQS 2006 field campaigns to compute total horizontal flux of ozone downwind of the Houston and Dallas metropolitan areas. Fluxes are computed for each transect by integrating excess ozone in the urban plumes (plume ozone - background ozone) between the surface and the top of boundary layer and between the horizontal plume edges and then multiplying the result with the horizontal wind speed provided by a nearby radar wind profiler. We will compare ozone flux measurements for Houston and Dallas under varying meteorological conditions and for different background ozone loadings. In addition, we will use data from multiple downwind transects to estimate ozone production rates in the Houston and Dallas plumes.
