GPM Ground Validation Environment Canada (EC) Micro Rain Radar (MRR) GCPEx Table of Contents
The GPM Ground Validation Environment Canada (EC) Micro Rain Radar (MRR) GCPEx data was collected by Environment Canada during the GPM Cold-season Precipitation Experiment (GCPEx) in Ontario, Canada during the winter season of 2012. Operating at 24 GHz, the MRR is a vertically pointing Doppler radar which derives quantitative rain rates, drop size distributions, radar reflectivity and fall velocities on vertical profiles up to several kilometers above the unit. The MRR used during GCPEX is the second generation of the instrument manufactured by METEK. CampaignThe GPM Cold-season Precipitation Experiment (GCPEx) occurred in Ontario, Canada during the winter season of 2011-2012. GCPEx addressed shortcomings in the GPM snowfall retrieval algorithm by collecting microphysical properties, associated remote sensing observations, and coordinated model simulations of precipitating snow. These data sets were collected to aid in the achievement of the over arching goal of GCPEx which is to characterize the ability of multi-frequency active and passive microwave sensors to detect and estimate falling snow. During GCPEx, an MRR was located at each of the five sites in Ontario, Canada. The site names and locations are:
Data was collected from January 6, 2012 through March 1, 2012. Further details on GCPEx are available at http://gpm.nsstc.nasa.gov/gcpex. Information on the Global Precipitation Measurement (GPM) mission is available at http://pmm.nasa.gov/GPM. Additional campaign collections containing MRR data can be found at http://ghrc.nsstc.nasa.gov. Instrument DescriptionThe EC MRR is a frequency-modulated continuous wave (FMCW) vertically pointing Doppler radar, which operates at 24.24GHz. The MRR measures profiles of Doppler spectra and derives drop size distributions, rain rates, and liquid water rates. The MRR is the second generation of the instrument manufactured by METEK.
