IONS 06

Using the robust data set collected during the INTEX Ozonesonde Network Study (IONS06) along with total column ozone from the Total Ozone Mapping Spectrometer (TOMS) on the Ozone Monitoring Instrument (OMI) and aerosol backscatter (532 and 1064μm) from the Cloud-Aerosol LIDAR Infrared Pathfinder Satellite Observation (CALIPSO) and Aerosol Optical Depth from the Moderate Resolution Imaging Spectroradiometer (MODIS), a high-pollution plume will be identified on 20 August 2006.  Backward and forward trajectories using the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model will be used along with L4 meteorological data and IR images from GOES-12 to determine the origin and general motion of the detected plume in order to track the plume’s path.  A general pattern will be observed throughout the month of August of a region of relatively low ozone over the Plains States and a region of relatively high ozone over the Southeastern United States.  Using ozone profiles collected during IONS06 over the Eastern portion of the US and TOMS data a plume of high tropospheric ozone was detected and the track this plume takes will be identified.
