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.



GHRC’s application for membership in the International Council for Science (ICSU) World Data System (WDS) has been accepted by the WDS Scientific Committee (WDS-SC). Pending the finalization of a signed agreement with ICSU, GHRC will be a Regular Member of ICSU-WDS.


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To support the scientists in the field, the GHRC has developed a Drupal-based collaboration portal (no longer active) complete with instrument status reports, weather forecasts, schedules, mission reports, documents, and links to external datasets.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


GHRC has installed and configured a new disk-based Sun Storage 720 archive.  Systems administrators and data managers are planning directory layout, archive processes and migration from the existing tape-based Sun Storage L700 system.  The new archive will start with 100 TB (usable) and is scalable to up to 2.6 PB raw capacity.


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.
