GHRC News

Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC) Manager Dr. Rahul Ramachandran was a guest editor for the current edition of Earth Science Informatics, a special issue on Intelligent GIServices (Geographical Information Services). GHRC data management group member Kaylin Bugbee was co-author of a paper in this issue, which describes the concept of intelligent GIServices, followed by a review of the state-of-the-art technologies and methodologies relevant to intelligent GIServices including capabilities such as knowledge representation, semantic reasoning, automatic workflow composition, and quality and traceability.

The Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC) published three Micro Rain Radar (MRR) datasets in the Global Precipitation Measurement (GPM) Ground Validation collection. 

GPM Ground Validation Micro Rain Radar (MRR) NASA IPHEx

GPM Ground Validation Micro Rain Radar (MRR) NASA IFloodS

GPM Ground Validation Micro Rain Radar (MRR) NASA HyMeX

The MRR is a vertically pointing Doppler radar which provides measurements of vertical velocity, drop size distribution, rainfall rate, attenuation, liquid water content, and reflectivity factor.  These datasets contain observations from MRRs deployed for the Integrated Precipitation and Hydrology Experiment (IPHEx), which took place in western North Carolina during the spring of 2014; the Iowa Flood Study (IFloodS), which took place in eastern Iowa during the spring of 2013; and the HYdrological cycle in Mediterranean EXperiment (HyMeX) in Italy, fall 2012.

The Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC) has published another core dataset in the Hurricane and Severe Storm Sentinel (HS3) collection. The HS3 Hurricane Imaging Radiometer (HIRAD) dataset contains ocean surface winds and precipitation observations from the HIRAD multi-band passive microwave radiometer. HIRAD uses novel interferometric aperture synthesis technique to produce high-resolution wide swath observations without any mechanical scanning of the antenna. The instrument was designed to measure ocean surface wind speed in tropical storms and hurricanes. Developed in collaboration between scientists and engineers at NASA MSFC, University of Central Florida and University of Michigan, the instrument was first flown on NASA high altitude aircraft in the Genesis and Rapid Intensification Processes (GRIP) Experiment in 2010 and Hurricane and Severe Storm Sentinel (HS3) in 2012-2014.

We have improved HyDRO, our data discovery and access tool! The updated design improves the user experience in navigating search results to find all relevant dataset information, including metadata and documentation, browse imagery, inventory listing and download location. This version of HyDRO also integrates the central NASA Earth Science Data and Information System (ESDIS) Earthdata Login (formerly called the EOSDIS User Registration System (URS)). Users can be steered through the Earthdata Login download data or place an order. Currently, login is only required for accessing selected datasets.
