Retrieval of total atmospheric ozone from GOES sounder radiance measurements with high spatial and temporal resolution

Abstract

The potential for using Geostationary Operational Environmental satellite (GOES) Sounder radiance measurements to monitor total atmospheric ozone is examined. A statistical regression using GOES channel 1 (4.7 μm), 2 (14.4 μm), 3 (14.1 μm), 4 (13.6 mu;m), and 9 (9.7 μm) radiances, followed by a physical iterative retrieval using only the channel 9 radiance, allows retrieval of total atmospheric ozone. Simulations show that the algorithm is suitable for retrieving total ozone with reasonable accuracy. At the conference, real GOES retrieved ozone values will be compared with total ozone mapping spectrometer ozone measurements from the Earth Probe satellite. Both qualitative and quantitative comparisons will show that the GOES retrievals are able to capture the main structure of the ozone distribution. Given the hourly measurements and high spatial density provided by the GOES Sounder, the potential use of GOES ozone retrievals and associated products is promising.
