Global observation of atmospheric ozone by satellite
In March 1977 infrared radiance data became available from a new series of satellites, the Block 5D Defense Meteorological Satellite Program (DMSP) system operated by the US Air Force. A multichannel filter radiometer (MFR) on the first satellite (F1) began transmitting simultaneous radiance measurements from the channels in the 9.6 ..mu..m ozone bands, 15-..mu..m carbon dioxide bands, 18- to 30-..mu..m rotational water vapor band, as well as from the atmospheric window near 12 ..mu..m. The sensor provides ozone measurements made with a cross-track scanning instrument. The measurements are made at a high spatial resolution and low noise levels. The infrared MFR sensor made both daytime and nighttime observations, with up to a maximum of 67,500 observations each day. A discussion of the accuracy of these satellite MFR total ozone measurements is given. Comparisons are made against a specially selected network of surface-based total ozone measurement observations, as well as total ozone measurements made by another satellite sensor. A map of satellite measured total ozone is presented and compared against the temperature analysis from radiosonde ascents made during the Southern Hemisphere winter. (JGB)
