Abstract : A near-real-time sounding of the atmosphere from the surface to less than or equal to 30 km may be obtained by combining atmospheric profiles from meteorological (met) satellite and a ground-based system for remotely sensing wind and temperature. This type of capability is essential for optimum use of Army assets such as artillery and defense against biological and chemical attack. This report describes the method for merging data from satellite and ground-based remote-sensing systems and briefly discusses the algorithms used to evaluate the combined soundings. The current software allows the user to generate output in a standard form or in the format of an artillery met message. Initial results of this merging method are compared with data from nearly coincident rawinsondes. Preliminary comparisons of individual combined and rawinsonde sounding pairs, and individual met message zones for a number of sounding pairs, give an initial insight into the technique and the satellite/ground-based system concept.
