Guide Published for NOAA Surface Meteorological Station MC3E Dataset

GHRC has published the guide for the GPM Ground Validation NOAA Surface Meteorological Station MC3E dataset. The data collected for the Midlatitude Continental Convective Clouds Experiment (MC3E) at the NOAA Southern Great Plains Facility includes wind speed and direction, temperature and humidity, and precipitation. The instruments gathering this data were a propeller wind monitor located 10 meters above the ground, a temperature and humidity sensor at the ground, and a tipping rain gauge at the ground.

GHRC Featured on EarthData for IFloodS

GHRC is supporting the ongoing Global Precipitation Mission (GPM) Ground Validation Iowa Flood Studies (IFloodS) Field Experiment with a collaboration portal for the mission science team which provides for near-real time data acquisition; data access, visualization and map-based display; and science and instrument status reports. IFloodS is featured on the EarthData web site as the DAAC Image of the Week.

GHRC Accepted as a ICSU-WDS Regular Member

GHRC’s application for membership in the International Council for Science (ICSU) World Data System (WDS) has been accepted by the WDS Scientific Committee (WDS-SC). Pending the finalization of a signed agreement with ICSU, GHRC will be a Regular Member of ICSU-WDS.

GCPEX APR-2 Dataset Released

GCPEX logo GHRC has released GPM Ground Validation Airborne Second Generation Precipitation Radar (APR-2) GCPEx dataset. The Second Generation Airborne Precipitation Radar (APR-2) is a dual-frequency (13 GHz and 35 GHz), Doppler, dual-polarization radar system. It has a downward looking antenna that performs cross track scans, covering a swath that is +/- 25 to each side of the aircraft path. Additional features include: simultaneous dual-frequency, matched beam operation at 13.4 and 35.6 GHz (same as GPM Dual-Frequency Precipitation Radar), simultaneous measurement of both like- and cross-polarized signals at both frequencies, Doppler operation, and real-time pulse compression (so that calibrated reflectivity data can be produced for large areas in the field during flight, if necessary). The APR-2 flew aboard the NASA DC-8 for the GPM Cold-season Precipitation Experiment (GCPEx) from 11 January to 25 February, 2012.

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.
