Case Studies
Web-Based Case Studies are a collection of meteorological data for specific events. They include WSR-88D radar, GOES satellite data, NCEP model data, Family of Services text data, upper-air and profiler data, and any contributed data sets. These case studies are being used in National Weather Service Offices and university classrooms across the United States for research and education. more >

CONDUIT
The Cooperative Opportunity for NCEP Data Using IDD Technology (CONDUIT) employs the LDM/IDD to make high-resolution model data sets, not currently available through the NCEP/NWSTG Channel of the NOAAPORT broadcast, to the U.S. Weather Research Program (USWRP) and university communities. more >

CRAFT
The Collaborative Radar Acquisition Field Test (CRAFT) is testing access and distribution of NEXRAD Level II data, in near-real time. The techniques are now being folded into the NWS Level II data distribution plans. more >

LEAD
The Linked Environments for Atmospheric Discovery (LEAD) is a NSF-funded multi-institutional large Information Technology Research effort. The goal of LEAD is to create an integrated and scalable framework for identifying, accessing, preparing, assimilating, predicting, managing, analyzing, mining, and visualizing a broad array of meteorological data and model output, independent of format and physical location. more >

netCDF/HDF Merger
Under a two-year award from the NASA Advanced Information Systems Technology program, Unidata and NCSA have collaborated to combine the netCDF interface with the HDF5 format in order to create and deploy software that will take advantage of the widespread use and simplicity of netCDF and the generality and performance of HDF5. more >

NLDM
Unidata is investigating the use of the NNTP-based Local Data Manager for the purpose of data relay. An early report of the reasons for this effort and its viability is available at On the Use of Internet News for Delivering Data. more >
|
THREDDS
The THREDDS (Thematic Realtime Environmental Distributed Data Services) project is developing middleware to bridge the gap between data providers and data users. The goal is to simplify the discovery and use of scientific data and to allow scientific publications and educational materials to reference scientific data. more >

SuomiNet
SuomiNet is a network of GPS receivers located at universities and other locations to provide realtime atmospheric precipitable water vapor measurements and other geodetic and meteorological information. Unidata is collaborating with COSMIC/UNAVCO on this project and is funded by the NSF. more >

CONDUIT
As of December 1, 2005 the CONDUIT data feed is currently being received by at least 80 unique hosts in 50 domains including sites in the United States, Brazil and Portugal. Sites reporting reception include research and education universities, government facilities and laboratories, as well as both commercial and nonprofit organizations. more >

LEAD
A principal function of the LEAD Grid is to host data sets of relevance to mesoscale meteorology. Each grid node runs the Unidata LDM/IDD software to ingest a variety of data sets include those from NEXRAD radars, upper-air balloons, geostationary satellites, surface networks, commercial aircraft, wind profilers, and other systems. more >

netCDF/HDF Merger
The effectiveness of the netCDF/HDF merged software will be demonstrated by its use in advanced modeling efforts, including CCSM and WRF. Development plans for the two models include goals for creating I/O frameworks that support high levels of parallelism while promoting interoperability. These initiatives provide an ideal test bed on which to evaluate the design and implementation of the new HDF5-based netCDF-4 library.

THREDDS
One of the primary objectives of the THREDDS Data Server (TDS) is to serve real-time meteorological data from Unidata's Internet Data Distribution (IDD). To use the TDS in this way, you must install and run Unidata's LDM, and connect to the IDD. more >
