Two Similar GPM Datasets Published

GHRC published two similar datasets associated with the Global Precipitation Measurement (GPM) Ground Validation program: GPM Ground Validation Composite Satellite Overpasses MC3E and GPM Ground Validation Composite Satellite Overpasses GCPEX. Each of these datasets provide data from satellite overpasses of the study region for the mission Midlatitude Continental Convective Clouds Experiment (MC3E), Oklahoma 2011, or the GPM Cold-season Precipitation Experiment (GCPEx), Canada 2012. The radiometric data was matched up with other datasets necessary to carry out land surface emissivity studies. These other datasets include the NEXRAD NMQ radar mosaic for knowledge of rain structure and intensity at the time of the overpass, as well as the previous accumulated precipitation prior to the satellite overpass time), the NOAA IMS snow mapping system (to identify surface snow or ice cover), and the NASA/GMAO MERRA land and atmospheric reanalysis (for background land and atmospheric state needed for microwave radiative transfer calculations). The AQUA satellite overpasses were used for MC3E and SSMIS for GCPEX, passing within 700-km of the central field site.
