GHRC has released the GPM Ground Validation Environment Canada (EC) Micro Rain Radar (MRR) GCPEx dataset. Environment Canada (EC) collected data from the Micro Rain Radar (MRR) during the GPM Cold-season Precipitation Experiment (GCPEx) in Ontario, Canada during the winter season 2012. Operating at 24 GHz the MRR, a vertically pointing Doppler radar, retrieved quantitative rain rates, drop size distributions, radar reflectivity, fall velocities on vertical profiles up to several kilometers above the unit.
