At present, the USGS is monitoring geometeorological conditions in different types of deserts in Arizona, using data relayed by satellite from solar-powered Geomet stations. These stations consist of automated data-collection platforms coupled with an array of sensors that measure boundary-layer atmospheric and geologic conditions at frequent intervals, around the clock. Such data are essential to studies of surface geologic processes in deserts, particularly wind erosion, and of the landforms that develop in response to these processes. The Geomet data are also of interest to the U.S. Army, which must operate in various types of deserts and therefore needs information related to natural hindrances to cross-country movement, selection of aircraft landing sites, cover and concealment, camouflage, dust generation, and location of usable water. The U.S. Army Engineer Topographic Laboratories, Center for Remote Sensing ETL-CRS, has evaluated a variety of remote sensors and image-analysis techniques in subhumid regions, and a part of its research program is directed toward applying these techniques to the Armys need for information on desert terrain. The complementary research needs of the USGS and ETL-CRS resulted in a workshop held in Flagstaff, Ariz., on September 24-28, 1984.
