The estimate uses a regression on Sounder brightness temperatures, viewing angle, time of year, and surface pressure to determine the ozone profile, from which the total column ozone value is calculated. The regression coefficients were generated from the NOAA88 set of temperature, moisture, and ozone profiles. Figure 55 illustrates a typical ozone estimate product from the GOES Sounder. Spatial resolution of the product is approximately 30 kilometers and temporal resolution is one hour. Regions with thick or cold clouds are not processed by the ozone estimation algorithm and are shown with a gray enhancement.
Several features corresponding to synoptic scale weather systems are visible.
The spatial distribution of ozone is well captured, though the absolute magnitudes tend to be less accurate in areas with dry air and widely varying diurnal temperatures. As a result, the ozone estimate product is most reliable over the oceans and where surface temperatures are the most stable. This product is not yet operational, though it is expected to be used by modelers, universities, and NWS and DoD forecasters. Preprints, 1st Intl.
