Welcome to the Madrigal Database
at Arecibo Observatory
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 Institute of Geodesy and Geophysics, the Chinese Academy of Sciences, 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.
