Paper Abstract

The development of the techniques for spaceborne detecting gas anomalies in the lower atmosphere is very important. The results of the Kioto protocol, an extended use of hydrocarbon raw material, the occurrence of new chemical emissions call for further realization of global control over gaseous contaminations in the atmosphere. A spaceborne location of sensors is very promising for solving this problem. In this case the light automatic satellites, oriented to a limited area of application, are the most promising. As a rule, for such satellites the orbits at 500 km altitude and more are selected. This altitude and small mass of a satellite impose severe requirements on the efficiency of the techniques and apparatus realizations. Taking account of the last-named fact, the paper describes the use of the differential absorption method with a reflection from the Earth's surface for global monitoring of gaseous contaminations. The experiments were performed to assess lidar detection of ground anomalies of hydrocarbons in the 3-5 micrometers transmittance window. It is shown that, as applied to a spaceborne platform MKA- 200, this technique provides for localization of the background concentration excess of gases of hydrocarbon cycle with an error from 15% to 25%.
