"Real-time Air Quality Modeling: Chemical and Aerosol Assimilation and Forecasting Studies during the 2008 NOAA ARCPAC Field Mission"
R. Bradley Pierce, National Oceanic and Atmospheric Administration
During April 2008, NOAA’s Climate Forcing and Air Quality Programs engaged in an airborne field measurement campaign in the Alaskan Arctic. The Aerosol, Radiation, and Cloud Processes affecting Arctic Climate (ARCPAC) field mission focused on direct measurements of properties and processes designed to address four major areas of non-greenhouse-gas atmospheric climate forcing. The Real-time Air Quality Modeling System (RAQMS) chemical and aerosol forecasts were used for daily flight planning activities during ARCPAC. This talk presents results from post mission studies focused on integration of RAQMS analyses, satellite, ground based, and airborne observations for evaluation of the impacts of long-range transport of anthropogenic pollution and halogen chemistry on the chemical and aerosol composition of the Arctic.
