Japan's Role for the Global Precipitation Measurement
Abstract
GPM consists of a core satellite and a constellation of small satellites equipped with microwave radiometers. The core satellite will have a dual wavelength radar (DPR) and will be used to tune and train the microwave radiometer rain estimates. For the space segment of GPM, Japan plans to take a role of DPR development with collaboration of the Communications Research Laboratory, and the launch of the core satellite. Compared with tropical regions, mid- and high- latitude regions have weaker precipitation and snow or ice precipitation, and higher sensitivity and a capability of discrimination of liquid and solid hydrometeors are required for the radar.
