Abstract: Path-averaged terminal velocity distribution of raindrops is determined from the temporal covariance function of signals from two vertically spaced linear optical detectors that respond to raindrop-induced amplitude ...

Abstract: The possibility of identifying weather through the observation of forward scatter of a laser beam has been investigated. Preliminary observations with a prototype instrument suggest that it is possible to distinguish clear ...

Abstract: Remote sensing instrumentation has advanced to the point where serious consideration is being given to a next-generation tropospheric sounding system that uses radars and radiometers to provide profiles of tropospheric ...

Abstract: A remote-sensing system for continuously profiling the troposphere is discussed; the prototype Profiler utilizes radio wavelengths, thereby achieving essentially all-weather operation. Designed for unattended operation, ...
