IFloodS logoThe official start of the Global Precipitation Mission (GPM) Ground Validation Iowa Flood Studies (IFloodS) Field Experiment begins on May 1, 2013. See 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To support the scientists in the field, the GHRC has developed a Drupal-based collaboration portal (no longer active) complete with instrument status reports, weather forecasts, schedules, mission reports, documents, and links to external datasets.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.


GRIP logo

GHRC updated the  documentation for the GRIP Hurricane Imaging Radiometer (HIRAD) dataset with information about the new files containing rain rates and wind speed from Hurricane Earl (September 1-2, 2010). Data with these geophysical parameters are now distributed along with the original brightness temperature files.  The HIRAD flew aboard the WB-57 aircraft from Houston, Texas during the Genesis and Rapid Intensification Processes (GRIP) experiment.


Sample browse imageGHRC 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. 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.


The initial phase of the Iowa Flood Studies field campaign has begun.  IFloodS is the first of several hydrology-oriented field efforts that the GPM Ground Validation (GV) program is conducting.   GHRC is providing a collaboration portal for the field campaign team to exchange data and information including instrument status, mission science reports, weather forecasts and preliminary science data.  We have already begun collecting instrument data and model output for the region.  More instruments will come online throughout April in preparation for the official start of the campaign on May 1.  During the field campaign, access to the collaboration portal  and quicklook data is restricted to team members.  We expect to begin receiving and publishing quality controlled data products from the mission in approximately six months.
