Cloud Observation with CRL Airborne Cloud Radar (SPIDER)

摘要

Cloud plays an important role of the transmission of radiation energy, but it was still remains with uncertainty. It is expected to observe three-dimensional distribution of cloud. Although it is difficult with usual weather radar, Communications Research Laboratory developed an Airborne Cloud Profiling Radar (SPIDER). Its sensitivity is -35 dBZ at 5 km range. In this paper, observation theory and method are discussed. Effectiveness of cloud profiling radar is explained with cloud data, which was obtained with airborne measurement.
