GPM Ground Validation Environment Canada (EC) Radiometer GCPExTable of Contents
The GPM Ground Validation Environment Canada (EC) Radiometer GCPEx data set contains temperature, water vapor, relative humidity and liquid water profiles that were acquired by a Radiometrics TP-3000 passive microwave radiometer. The data were collected during the GPM Cold-season Precipitation Experiment (GCPEx) in Ontario, Canada, from February 14, 2012 to March 1, 2012. The GPM Ground Validation Environment Canada (EC) Radiometer GCPEx data files are available in comma-delimited ASCII files. Browse files for this data set are also available. The browse files feature plots of water vapor, temperature, relative humidity and pressure. 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, a TP-3000 radiometer was located at the CARE site in Ontario, Canada. The location of the CARE site is:
Data was collected from February 14, 2012 to 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. Instrument DescriptionThe Radiometrics TP-3000 is a passive radiometer that provides continuous temperature and humidity profiles up to 10 kilometers in height. The TP-3000 also generates a one-layer cloud liquid profile. The water vapor and temperature profiling systems observe at selected frequencies between 22-30 GHz and 51-59 GHz. The TP-3000 also measures cloud base temperatures, surface pressure, surface temperature, and humidity. More information on the Radiometrics TP-3000 can be found in the Product Sheet document.

where, Data Format The GPM Ground Validation Environment Canada (EC) Radiometer GCPEx data files are available in comma-separated ASCII files. The data files are considered level 2 files. More information on the column definitions of level 2 files can be found on page 61 of the Radiometrics TP3000 Operator's Manual. The GPM Ground Validation Environment Canada (EC) Radiometer GCPEx browse files are available in .png format. The browse files are plots of water vapor, temperature, relative humidity and pressure. The browse files were generated by Edwin Campos of the Argonne National Laboratory.
