Ajinkya Kulkarni discusses Drupal with colleagues
One of the meeting venues

Michael Goodman (NASA/MSFC; GHRC DAAC Manager) and Helen Conover (UAH/ITSC; GHRC Operations Manager) represented GHRC at the ESIP Federation Assembly, held in Chapel Hill, NC, July 9-12. As always, the meeting offered opportunities for valuable interactions with colleagues from NASA and other data systems. Mr. Goodman participated in sessions concerned with Earth science applications, information systems and computing, and natural disaster response. Ms. Conover participated in sessions addressing current issues in data stewardship, data discovery and metadata standards. She presented a poster entitled “GPM Ground Validation Field Campaigns: Collaboration and Data Management Tools.” GHRC-affiliated researchers Manil Maskey and Ajinkya Kulkarni (both UAH/ITSC) presented in the Disaster Response and Drupal Lab sessions, respectively. Mr. Maskey’s poster was “Coastal Hazards Event Drive Automated Data Aggregation, Processing and Delivery.” The GHRC team also attended an off-site, after-hours side meeting with NASA HQ at the Durham Bulls Athletic Park. Additional GHRC team members attended selected sessions remotely.

The GHRC has completed the MSFC-mandated upgrade of all web servers to Internet Protocol version 6 (IPv6).  IPv6 was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion.

GCPEX logoGHRC has published the GPM Ground Validation Compact Scanning Millimeter-wave Imaging Radiometer (CoSMIR) GCPEx dataset. The CoSMIR plays the role as an airborne high-frequency simulator for the GPM Microwave Imager (GMI), which will launch in 2014.  The CoSMIR was modified with a new scan mode to acquire both conical and cross-track scan data simultaneously in a given flight satisfying the requirements of the Precipitation Measurement Mission (PMM) algorithm development team.  This CoSMIR dataset provides well-calibrated radiometric data from 9 channels between 50-183GHz with the  accuracy on the order of +-1K.  All channels besides the 89 and 165.5 GHz are horizontally polarized.
