GPM GROUND VALIDATION CHILL RADAR MC3E V1

The GPM Ground Validation CHILL Radar MC3E dataset was collected during the Midlatitude Continental Convective Clouds Experiment (MC3E), which was held in Oklahoma were collected while the NASA ER-2 aircraft conducted a series of four legs along the 090 and 120 degree CHILL azimuths on May 24, 2011. Dual linear polarization variables as well as Doppler velocity, radial velocity, and normalized coherent power are contained in this dataset. In an effort to expand the MC3E sampling to a wider geographical area, the NASA ER-2 aircraft was directed to Northeastern Colorado while widespread rain was in progress on May 24, 2011. The aircraft flew a series of pre-defined ground tracks that coincided with radials from the CSU-CHILL radar. This aided in keeping the aircraft in the plane of a series of RHI scans done by CSU-CHILL. The single polarization CSU-Pawnee radar maintained volume coverage of the echo system while the radial flight legs were in progress. During aircraft course reversals at the ends of the radial legs, the CHILL and Pawnee radars started volume scans in synchronization to support dual Doppler wind syntheses. The Pawnee radar data are available as a seperate dataset.

GPM GROUND VALIDATION DUAL POLARIZATION RADIOMETER GCPEX

The GPM Ground Validation Dual Polarization Radiometer GCPEx dataset includes brightness temperature measurements at frequencies 90 GHz (not polarized) and 150 GHz (HV-polarized) for the GPM Cold-season Precipitation Experiment (GCPEx) which occurred in Ontario, Canada. GCPEx addressed shortcomings in the GPM snowfall retrieval algorithm by collecting microphysical properties, associated remote sensing observations, and coordinated model simulations of precipitating snow. This dual polarization radiometer (DPR) is sensitive to particle orientation since it observes the brightness temperature difference between the vertical and horizontal polarization channels at 150 GHz, and it is especially important for the retrievals of particle shape and orientation with polarization observations. DPR also has a high sensitivity to the supercooled liquid water in clouds due to the high-frequency window channels. Even though the netCDF data has regular scans, the browse images are only shown at 30 and 150 degrees. Ancillary data was also captured for the internal calibration of the instrument.

GPM Ground Validation Dual-frequency Dual-polarized Doppler Radar (D3R) OLYMPEX

The GPM Ground Validation Dual-frequency Dual-polarized Doppler Radar (D3R) OLYMPEX dataset contains radar reflectivity, velocity, differential reflectivity, differential phase, spectrum width, and co-polar correlation products collected during the Global Precipitation Measurement mission (GPM) Ground Validation (GV) Olympic Mountains Experiment (OLYMPEX). The OLYMPEX field campaign took place between November 2015 and January 2016, with additional ground sampling continuing through February 2016, on the Olympic Peninsula in the Pacific Northwest of the United States. The purpose of the campaign was to provide ground-validation data for the measurements taken by instrumentation aboard the GPM Core Observatory satellite. The Dual-frequency Dual-polarized Doppler Radar (D3R) was developed by a government-industry-academic consortium with funding from NASA’s GPM mission and was used in several ground validation projects. D3R operates at the Ku-band (13.91 GHz ± 25 MHz) and Ka-band (35.56 GHz ± 25 MHz) frequencies, similar to the frequencies used for the GPM satellite instruments, and covers a fixed range from 450 m to 40 km. For OLYMPEX, the D3R was co-located with the NASA S-band Dual Polarimetric (NPOL) Doppler Radar at a coastal Washington state location on the Olympic Peninsula. Due to blockage caused by NPOL, the D3R measurement area is limited to a 220 degree to 120 degree sector. The GPM GV D3R OLYMPEX dataset files are available from November 8, 2015 through January 15, 2016 in netCDF-4 format along with browse imagery of reflectivity in PNG format.
