Investigation of Distributed Environmental Archives System

Go to IDEAS

IDEAS

The Investigation of Distributed Environmental Archives System (IDEAS) is a network distributed software system designed to allow a user to interact with archives of environmental data for the purpose of scenario extraction, data analysis and integration with existing models that require environmental input. The IDEAS uses fuzzy-logic based search tools to allow a user to look for specific environmental scenarios in vast archives by specifying the search in human linguistic terms. For example the user can specify a scenario such as a "cloud free week" or "high winds and low pressure" and then search relevant archives available across the network to get a list of matching events. The IDEAS hooks to existing archives of data by providing a simple communication frame work and an efficient data model for exchanging data. Once data has been delivered by the distributed archives in the IDEAS data model it can easily be accessed by the visualization, integration and analysis components to meet specific user requests. The IDEAS implementation provides a frame work which can be taken as a pattern applicable to other distributed archive systems.

IDV

The Integrated Data Viewer (IDV) from Unidata is a software library package and software framework for visualizing and analysing geoscience data. This IDV release includes a Java(TM)-based software library, and a reference application made from that software. It uses the VisAD library (http://www.ssec.wisc.edu/~billh/visad.html) for data models and for creating visualizations, and other Java-based utility packages. The IDV is created at the Unidata Program Center (UPC), part of the University Corporation for Atmospheric Research, Boulder, Colorado, which is funded by the National Science Foundation. The software is freely available under the terms of the GNU Lesser General Public License. The IDV brings together the ability to display and work with satellite imagery, gridded data (for example, numerical weather prediction model output, and many Climate Diagnostics Center grids), surface observations (METARs), balloon soundings, NWS NEXRAD Level II and Level III RADAR data, and NOAA National Profiler Network data, all within a unified interface. The IDV can display any Earth-located data if it is provided in a valid netCDF file with sufficient navigation metadata (see Data Formats). The IDV is used by numerous US colleges and universities, and by research projects in other countries.

ESG

The Environmental Scenario Generator (ESG) project is sponsored by the Defense Modeling and Simulation Office, as part of the Integrated Natural Environment project. The Environmental Scenario Generator is intended to provide an integrated, physically consistent environmental data set meeting a Modeling and Simulation (M&S) customer's requirements for an authoritative and realistic representation of atmospheric, oceanic, and/or space natural environment elements for specified regions, time frames, and conditions.
