GCPEX MRR Dataset Released

Sample browse image 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.

New Storage Archive Installed and Configured

GHRC has installed and configured a new disk-based Sun Storage 720 archive. Systems administrators and data managers are planning directory layout, archive processes and migration from the existing tape-based Sun Storage L700 system. The new archive will start with 100 TB (usable) and is scalable to up to 2.6 PB raw capacity.

Documentation Completed on Various MC3E Datasets

MC3E logo GHRC has completed documentation for the four GPM Ground Validation NOAA S-Band Profiler datasets and two GPM Ground Validation NOAA UHF 449 Profiler datasets from the Midlatitude Continental Convective Clouds Experiment (MC3E), a GPM Ground Validation field campaign.

GCPEX 2DVD Dataset Released

GHRC added the GPM Ground Validation Two-Dimensional Video Disdrometer (2DVD) GCPEx dataset to its GPM GCPEX dataset collection. Collected from six sites in Ontario, Canada, the data contains daily ASCII files with information on individual snowflakes and hydrometeors, and also binary files preprocessed from raw camera data. Overall data dates range from 27 October 2011 through 27 February 2012 depending on the specific site. GHRC also has related 2DVD datasets for data from the LPVEX and MC3E experiments and data collected at the National Space Science and Technology Center (NSSTC).

IFloodS Field Campaign Begins Initial Phase

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.
