An Evaluation of Stratosphere-Troposphere Ozone Exchange During TOPSE Using GOES Derived Product Images

The integration of newly developed GOES derived product images to TOPSE flight measurements allows for a more complete characterization of stratosphere-troposphere exchange along tropopause folds. The aircraft-based dIfferential absorption lidar (DIAL), ozone retrievals and co-located potential vorticity (PV) from the RUC-2 atmospheric model improves our understanding of the direct relationship between PV and stratospheric ozone. We shall examine the transport of PV/ozone in one-hour timesteps described by the RUC-2 model. The distribution of PV/ozone is validated independently with the GOES altered water vapor product, GOES total ozone product and TOMS total ozone product. Using these derived product images, we can begin to estimate the frequency and intensity of STE in the northern midlatitudes over the TOPSE period of February to May, 2000.
