Welcome to the CEDAR Archival Madrigal Database

The is the archival Madrigal site, where all data from all Madrigal sites is automatically imported for archiving. Since all Madrigal data from all sites is local here, you can use the Simple Local Data Access link to search for all Madrigal data from any site. Using the Full Data Access link will allow you to search data in the normal way, where your search will take you to the host Madrigal site.

Madrigal is an upper atmospheric science database used by groups throughout the world. 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.

Data can be accessed from a variety of Madrigal sites, including (but not limited to) Millstone Hill, USA, Arecibo, Puerto Rico, EISCAT, Norway, SRI International, USA, Cornell University, USA, Jicamarca, Peru, ,the Consortium of Resonance and Rayleigh Lidars, the Institute of Geodesy and Geophysics, the Chinese Academy of Sciences, the University of Oulu, Finland, and finally, the archival CEDAR site. To see a list of all Madrigal sites, choose Full Data Access and select Go to a different Madrigal site. Data can also be accessed directly, using APIs which are available for several popular programming languages (Matlab, python, and IDL). A Subversion archive of all Madrigal software and documentation is available from the Open Madrigal Web site. The latest version of Madrigal and the remote API's may also be downloaded from there.

Data are often subject to limitations which are not immediately evident to new users. Before they are formally submitted, draft copies of all reports and publications must be sent to the contact scientist at all data-supplying organizations along with an offer of co-authorship to scientists who have provided data. This offer may be declined. The Database and the organizations that contributed data must be acknowledged in all reports and publications, and whenever this data is made available through another database.
