IFloodS Field Campaign Begins This Week

IFloodS logo The official start of the Global Precipitation Mission (GPM) Ground Validation Iowa Flood Studies (IFloodS) Field Experiment begins on May 1, 2013. See https://ghrc.nsstc.nasa.gov/home/field-campaigns/ifloods for the experiment overview.

To support the scientists in the field, the GHRC has developed a Drupal-based collaboration portal (no longer active) complete with instrument status reports, weather forecasts, schedules, mission reports, documents, and links to external datasets.

Numerous datasets and browse images have been ingested and uploaded to a Public FTP server (registration required) and the majority of those native datasets have been loaded into either a THREDDS (Thematic Realtime Environmental Distributed Data Services) data server or GeoServer (an open source software server written in Java that allows users to share and edit geospatial data) for display on either a 2D Mercator or 3D Globe. In addition, four of the NEXRAD (Next-Generation Radar) Level-2 datasets are being “animated” to show the last ten images in motion.

GCPEX Meteorological Tower Environment Canada Dataset Released

Sample browse image GHRC has released the GPM Ground Validation Meteorological Tower Environment Canada GCPEx dataset as part of the GPM Cold-season Precipitation Experiment (GCPEx) where data was gathered over the Ontario region of Canada in 2012 from Jan 15 through March 1. This dataset provides temperature, relative humidity, 10m winds, pressure and solar radiation data collected by a suite of standard meteorological instruments attached to a 10m met tower. The observation station was assembled by Automated Transportable Meteorological Observation Station (ATMOS). Browse images are available on-line.

Dr. Ramachandran Elected as Chair of IEEE GRSS DAD TC

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 Represented at CODATA meeting in Paris

Dr. Sara Graves represented the GHRC at the International Council for Science : Committee on Data for Science and Technology (CODATA) Executive Committee meeting in Paris the week of April 14th as the Secretary General of CODATA. There were discussions with Dr. Steven Wilson, Executive Director of The International Council for Science (ICSU), about Future Earth and the data aspects of that large 10 year program. She also met with some representatives from the World Data System on collaborations on Future Earth and several other activities. Lastly, a presentation titled ‘Using GLIDER for Data Intensive Science’ by Sara Graves, Todd Berendes and Rahul Ramachandran was made at the European Geosciences Union (EGU) General Assembly in Vienna, Austria on April 8th, 2013.

GHRC Represented at Data Discovery Technical Interchange Meeting

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.
