The Open Madrigal Initiative
The OpenMadrigal project develops and supports the Madrigal database, which is a community resource for geospace data. The project has been led by MIT Haystack Observatory since 1980, and is now supported by the NSF and other community members. Madrigal is a robust, World Wide Web based system capable of managing and serving archival and real-time data, in a variety of formats, from a wide range of ground-based and some space-based instruments. Madrigal is installed at a number of sites around the world, and has a central archive site at the CEDAR Madrigal database. Data at each Madrigal site is locally controlled and can be updated at any time, but shared metadata between Madrigal sites allow searching of all Madrigal sites at once from any Madrigal site.
