GHRC has published the GPM Ground Validation Environment Canada (EC) Precipitation Occurrence Sensor System (POSS) GCPExdataset. Data was gathered during the GPM Cold-season Precipitation Experiment which took place in Ontario, Canada, January 15 - March 1, 2012. The POSS is a bi-static X-band Doppler radar designed by Environment Canada. The POSS measures a signal whose frequency is proportional to the particle Doppler velocity and whose amplitude is proportional to the particle scattering cross-section. Its measurements can be used provide information regarding precipitation occurrence, type, rate, and raindrop size distribution.
