GCPEx

GHRC has released a Guide supporting two similar datasets for the GCPEX and MC3E campaigns: GPM Ground Validation NCAR Cloud Microphysics Particle Probes. Both datasets provide data from three instrument probes carried aboard the University of North Dakota (UND) Cessna Citation aircraft. These probes, the 2D-C, Cloud Imaging Probe (CIP) and High Volume Precipitation Spectrometer (HVPS-3), collected particle size distributions and particle images which were processed by NCAR. Derived parameters include ice water content, liquid water content, and total number concentration. The GPM Cold-season Precipitation Experiment (GCPEx) took place in Ontario, Canada during the winter season of 2011-2012, and the Midlatitude Continental Convective Clouds Experiment (MC3E) occurred in central Oklahoma during the April-June 2011.

GHRC published the guide for the GPM Ground Validation Dual Polarized C-Band Doppler Radar King City GCPEx dataset. This dataset has special RHI and sector scans of several dual polarization parameters created by the C-Band radar during the GPM Cold-season Precipitation Experiment (GCPEx) in Ontario, Canada. Additionally, specially configured CARE-centric composites were also generated. Standard WKR IRIS volume and PPI scans, along with corresponding standard PPI imagery, are also included. Data was collected from January 15, 2012 through March 3, 2012.

GHRC has published the GPM Ground Validation CARE Satellite Overpass Images GCPEx dataset provides satellite overpass images for the Environment Canada’s Centre for Atmospheric Research Experiments (CARE) site in Ontario, Canada, as part of the GPM Cold-season Precipitation Experiment, January and February, 2012. The satellites tracks include the DMSP satellites numbers 15, 16, 17, 18, and 19. A list of starting overpass times per satellite and day is included.

GHRC published the GPM Ground Validation Advanced Microwave Radiometer Rain Identification (ADMIRARI) GCPEx dataset which measures brightness temperatures at three frequencies (10.7, 21.0 and 36.5 GHz) and at two polarized planes (H & V). The ADMIRARI is a scanning radiometer like its auxiliary active instruments, i.e., Micro rain radar and cloud lidar which provide reflectivity profiles and cloud base altitude at the same scanning angle as the radiometer. The radiometer retrieval typically provides rain/cloud liquid water path (LWP) and integrated water vapor, and for low water content cases it provides the total LWP and integrated water vapor. This data was collected during the GPM Cold-season Precipitation Experiment (GCPEx) located in Ontario, Canada, January 14, 2012 through February 29, 2012.

GHRC has published the guide for the GPM Ground Validation Environment Canada Snow Depth Surveys GCPEx dataset including dataset specific citation and DOI. The dataset was manually collected during the GPM Cold-season Precipitation Experiment (GCPEx) which occurred in Ontario, Canada, January 20, 2012 through February 27, 2012 across four sites (CARE, Steamshow, Huronia Airport, and Skydive-Jump). Snow depth, water equivalent and density transects were surveyed weekly at each of the GCPEx sites in order to provide baseline information on the distribution of snow on the ground. Pairs of bulk density and snow water equivalent measurements were made every 25 m along the same transect using an ESC-30 (30 cm2 cross sectional area) snow corer. Snow depth measurements were made every 50 cm along a 100 m transect using a GPS equipped snow depth probe.

GHRC has published the GPM Ground Validation Dual-frequency Dual-polarized Dopper Radar (D3R) guide for two missions: Iowa Flood Studies (IFloodS) and the GPM Cold Season Precipitation Experiment (GCPEx). The D3R is a fully polarimetric, scanning weather radar system operating at the nominal frequencies of 13.91 GHz and 35.56 GHz covering a maximum range of 30 km. The Doppler velocity, radar reflectivity, and spectrum width are provided in the data in the netCDF format. Browse images are also available in .png format.
