AB: This talk presents a summary of chemical data assimilation studies utilizing the Real-time Air Quality Modeling System (RAQMS) to characterize trans-pacific pollution transport, photochemistry and continental US air quality during the 2006 NASA INTEX-B field mission. The RAQMS chemical analysis includes assimilation of cloud cleared OMI total column ozone measurements and ozone and carbon monoxide profiles from TES nadir global survey measurements. The chemical analyses are used in conjunction with airborne, surface and satellite measurements to show evidence of upper tropospheric pollution fluxes and efficient mixing of polluted and stratospheric air masses over the central Pacific, and enhanced pollution along the west coast of the US.
