New THREDDS Data Server Implemented

A new THREDDS data server, to supplement the OPeNDAP data server already in place, provides improved usability such as OGC-compliant web map services (WMS) to support interactive visualization requests, and a THREDDS catalog to help provide interoperability with other community tools and applications. Using THREDDS, WMS is able to produce an image for a specific time request into an aggregated dataset, i.e., treating a dataset as a single continuous entity without having to reference individual daily files. The new WMS capability for DISCOVER MEaSUREs SSMIS data is already being used in a UAH research project. The NSF-funded Northern Gulf Coastal Hazards Collaboratory is using the Event Driven Data Delivery (ED3) framework to support a visualization and situational awareness tool during storm events that affect the Northern Gulf Coast. The tool aggregates various datasets pertinent to the event using ED3. Datasets include real or near-real time observations, models and analyses of atmospheric conditions around the location of the event. Since SSMIS datasets provide information about various atmospheric conditions for the Gulf Coast, visualization of these datasets using Web Map Services will strengthen the capabilities of the tool.

GPM Ground Validation NASA Micro Rain Radar (MRR) GCPEx Dataset Published

GHRC has published another GPM Cold-season Precipitation Experiment (GCPEx) dataset: GPM Ground Validation NASA Micro Rain Radar (MRR) GCPEx. This second generation MRR is a vertically pointing Doppler radar providing measurements of vertical velocity, drop size distribution, rainfall rate, attenuation, liquid water content, and reflectivity factor. The NASA MRR data was collected in Canada from late October 2011 through March 2013.

GHRC Represented at the ESIP Federation Assembly in NC

Ajinkya Kulkarni discusses Drupal with colleagues

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.
