GHRC News

MC3E logoGHRC 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.

 

Rahul Ramachandran presenting at a recent ESIP Federation meeting

Dr. Rahul Ramachandran has been elected to serve as the chair of the IEEE Geosciences & Remote Sensing Society's (GRSS) Data Archiving and Distribution Technical Committee (DAD TC) for a two-year term.  This committee provides recommendations and responses to issues related to the archiving and distribution of remotely sensed geospatial and geotemporal data.  More information is available at the committee’s web site [http://www.grss-ieee.org/community/technical-committees/data-archival-distribution/].  Hampapuram Ramapriyan of NASA ESDIS is the outgoing DAD TC Chair.  Dr. Ramachandran is a senior research scientist with the University of Alabama in Huntsville’s Information Technology and Systems Center (ITSC) and the Global Hydrology Resource Center, a NASA data center jointly operated by Marshall Space Flight Center and ITSC.

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.

Helen Conover and Rahul Ramachandran attended a Browse Imagery, Visualization, Data Discovery Technical Interchange Meeting in Hampton, VA, sponsored by NASA's Earth Science Data and Information Systems project.  The meeting was hosted by the NASA Langley Atmospheric Science Data Center, and involved several Earth science data centers including the Global Hydrology Resource Center, a partnership between NASA MSFC and UAH ITSC.  Ms. Conover presented systems currently in operation at GHRC, while Dr. Ramachandran showed current ITSC research slated to be adopted at GHRC in the future. Discussions with the other DAACs and the GIBS team explored possibilities for future collaboration.

 

GCPEX logoGHRC 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.
