GHRC updated the documentation for the GRIP Hurricane Imaging Radiometer (HIRAD) dataset with information about the new files containing rain rates and wind speed from Hurricane Earl (September 1-2, 2010). Data with these geophysical parameters are now distributed along with the original brightness temperature files. The HIRAD flew aboard the WB-57 aircraft from Houston, Texas during the Genesis and Rapid Intensification Processes (GRIP) experiment.
GHRC has updated the GRIP Hurricane Imaging Radiometer (HIRAD) dataset with new files containing rain rates and wind speed from Hurricane Earl (September 1-2, 2010) as an addition to the original brightness temperature files.

GHRC has released the GPM Ground Validation Environment Canada (EC) Micro Rain Radar (MRR) GCPEx dataset. Environment Canada (EC) collected data from the Micro Rain Radar (MRR) during the GPM Cold-season Precipitation Experiment (GCPEx) in Ontario, Canada during the winter season 2012. Operating at 24 GHz the MRR, a vertically pointing Doppler radar, retrieved quantitative rain rates, drop size distributions, radar reflectivity, fall velocities on vertical profiles up to several kilometers above the unit.
The initial phase of the Iowa Flood Studies field campaign has begun. IFloodS is the first of several hydrology-oriented field efforts that the GPM Ground Validation (GV) program is conducting. GHRC is providing a collaboration portal for the field campaign team to exchange data and information including instrument status, mission science reports, weather forecasts and preliminary science data. We have already begun collecting instrument data and model output for the region. More instruments will come online throughout April in preparation for the official start of the campaign on May 1. During the field campaign, access to the collaboration portal and quicklook data is restricted to team members. We expect to begin receiving and publishing quality controlled data products from the mission in approximately six months.
GHRC published two radar datasets in support of NASA ER-2 instrumentation data for the Midlatitude Continental Convective Clouds Experiment (MC3E) held in Oklahoma in 2011. The GPM Ground Validation Pawnee Radar MC3E is a single polarization (V polarization) Doppler radar and the GPM Ground Validation CHILL Radar MC3E is a dual linear polarization Doppler Radar operated by Colorado State University. Data from both radars were collected while the NASA ER-2 aircraft conducted a series of four legs along the 090 and 120 degree CHILL azimuths when 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. The 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. CHILL and Pawnee radar data are available as separate datasets.
