Four GPM Satellite Simulated Orbit Datasets Published

GHRC has published 4 satellite simulated orbit datasets for GPM Ground Validation research as part of the Global Precipitation Measurement mission. The GPM Ground Validation Satellite Simulator Orbits Database datasets are available for several campaigns: Light Precipitation Evaluation Experiment (LPVEX), Midlatitude Continental Convective Clouds Experiment (MC3E) , Canadian Cloudsat/Calipso Validation Project (C3VP), and Tropical Warm Pool - International Cloud Experiment (TWP-ICE). This orbital database takes account for the atmospheric profiles, the cloud/rain profiles, and the detailed surface/terrain information from the Cloud-Resolving Model (CRM) database. Unique geometry and antenna gain patters of each sensor (GMI imager, GMI sounder, DPR Ku, DPR Ka_MA, DPR Ka_HS) are considered. The Orbital database consists of satellite orbit parameters, geolocation of IFOV/EFOV and satellite location, and simulated L1B/L2-like parameters in satellite orbital grid. Orbital data covers a portion of sampling right over the Cloud-resolving model (CRM) domain. All orbital data format is NetCDF3, and contains dimensions, parameter descriptions, and parameter units. Each project's data is distributed as a separate dataset. MC3E occurred in Oklahoma, USA in 2011; LPVEX took place in Finland in 2010; C3VP experiment was held in Canada in 2007; and TWP-ICE took place in Australia in 2006.

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.

GHRC Represented at the Earth Cube Real-time Workshop

Dr. Sara Graves and Ken Keiser represented GHRC at the Earth Cube Real-time Workshop in Boulder, CO, June 17-18. The workshop was held at UCAR and sponsored by NSF. GHRC presentations covered data management, visualization and collaboration activities for GPM Ground Validation; data provenance tools developed for the AMSR-E SIPS at GHRC; and new data search and analysis technologies being developed in the GHRC Innovations Laboratory.

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.

NAMMA Lightning ZEUS Data Guide Updated

GHRC has updated the guide for the NAMMA Lightning ZEUS Data dataset with information from the Principal Investigator. The NAMMA Lightning ZEUS Data gathered lightning data from the World-ZEUS Long Range Lightning Monitoring Network Data obtained from sferics located at thirteen ground stations spread across the European and African continents and Brazil for the NASA African Monsoon Multidisciplinary Analyses (NAMMA) campaign held in 2006 in the Cape Verde Islands, 350 miles off the coast of Senegal in west Africa.
