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.

New Storage Archive Installed and Configured

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.

GCPEX 2DVD Dataset Released

GHRC added the GPM Ground Validation Two-Dimensional Video Disdrometer (2DVD) GCPEx dataset to its GPM GCPEX dataset collection. Collected from six sites in Ontario, Canada, the data contains daily ASCII files with information on individual snowflakes and hydrometeors, and also binary files preprocessed from raw camera data. Overall data dates range from 27 October 2011 through 27 February 2012 depending on the specific site. GHRC also has related 2DVD datasets for data from the LPVEX and MC3E experiments and data collected at the National Space Science and Technology Center (NSSTC).

Guide for MC3E Dataset Complete

GHRC completed the guide for the GPM Ground Validation Oklahoma Climatological Survey Mesonet MC3E dataset. The data was collected by a network of weather stations in central Oklahoma during the Midlatitude Continental Convective Clouds Experiment (MC3E) in the April-June 2011 timeframe, and is composed of 15 minute and 5 minute files with one file per site per day in MTS format, the standard format used for mesonet data. Data can be read as ASCII text. Multiple parameters found in this dataset include relative humidity, air temperature, wind speed and direction, precipitation and calibrated soil moisture.

IFloodS Field Campaign Begins Initial Phase

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.
