GHRC has published Version 2 of the GPM Ground Validation Environment Canada (EC) Micro Rain Radar (MRR) GCPEx dataset. The data were collected GPM Cold-season Precipitation Experiment (GCPEx) in Ontario, Canada during the winter season 2012 and provide derived quantitative rain rates, drop size distributions, radar reflectivity and fall velocities on vertical profiles. The University of Wisconsin reprocessed the original raw spectra into the netCDF format using the Maahn method for netCDF conversion and also using the improved Maahn micro rain radar snow algorithm to convert the snow cases. Updated documentation is also provided.
