For over three years data from the Geostationary Operational Environmental Satellite (GOES) Sounder has been used to estimate total column ozone in real-time. Colocated, instantaneous ozone estimates from the Total Ozone Mapping Spectrometer (TOMS) and the GOES Sounder compare to within 4-7%. Gradients in the GOES Sounder total column ozone field depict ozone features in the atmosphere. TOMS observations, water vapor imagery, and potential vorticity fields are used to confirm these observations. Many atmospheric features, including tropopause folds, breaking synoptic waves, and jet streams, can be identified in real-time from GOES Sounder total column ozone imagery. Hourly GOES Sounder ozone estimates provide the first real-time glimpse of total column ozone dynamics over a large region at high spatial and temporal resolutions.
