Evaluation of GMI simulations with TES ozone data: the effects of different transport fields.

TES measurements of ozone reveal global patterns in the vertical distribution of tropospheric ozone, including the northern hemisphere pollution belt and the Middle East ozone maximum in summer, the great African plume in austral spring associated with emissions from biomass burning, and the ozone paradox associated with biomass burning emissions in the northern tropics. We use these observations to evaluate simulations of tropospheric ozone with the Global Modeling Initiative's model for transport and chemistry in the troposphere and stratosphere. We use two sets of meteorological fields for 2005, the GEOS- 4-DAS and GEOS-4-Forecast, to drive transport in the model, and we also compare the satellite data to results using the GEOS-4 GCM to drive transport. These fields are from Global Modeling and Assimilation Office of NASA/Goddard. We will analyze differences in ozone caused by the differences in meteorological fields.
