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
upper atmospheric science instruments. 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.

Madrigal is an upper atmospheric science database used by groups
throughout the world. A number of different datasets are located at this
repository.
