AB: The tropospheric ozone residual method is used to derive tropospheric ozone columns for the summer of 2005 based on the stratospheric ozone columns from Microwave Limb Sounder (MLS) measurements and the total ozone columns from Ozone Monitoring Instruments (OMI) measurements on NASA's Aura Mission. The results are evaluated by comparisons with available concurrent ozonesonde measurements. The results are then compared with regional air quality forecast model results over the United States and its surrounding oceans for summer 2005. Discrepancies will be discussed and the use of Aura tropospheric ozone columns in chemical forecasting for the United States will be addressed.
