GCPEX Precipitation Occurrence Sensor System (POSS) Dataset Published

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.
