CEDAR Madrigal Archive
As of 2012, the central CEDAR data archive is the CEDAR Madrigal Archive at http://cedar.openmadrigal.org. This central site provides a deep archive of all data at the various Madrigal sites, along with providing hosting and archiving for data sets not found on other Madrigal sites. All Madrigal sites, including the CEDAR Madrigal archive, share metadata, so users at any one Madrigal site can search for data sets on any Madrigal site. The CEDAR Madrigal Archive also hosts all data on the previous CEDAR data system (VSTO etc) which remains available with access links below. Contact Bill Rideout at email@example.com or Phil Erickson at firstname.lastname@example.org with any issues, or if you wish to have your data archived at the CEDAR Madrigal archive site. Please see the talk at the 2012 CEDAR Workshop given by Bill Rideout on 'Working with the new CEDAR Madrigal Archive Database' and his associated workshop page.
The non-archival Madrigal nodes as of 2012 are:
- Millstone Hill http://madrigal.haystack.mit.edu/madrigal
- EISCAT http://www.eiscat.se/madrigal
- SRI http://isr.sri.com/madrigal
- Jicamarca http://jro.igp.gob.pe/madrigal
- Arecibo http://madrigal.naic.edu/madrigal
- Cornell http://landau.geo.cornell.edu/madrigal
- The Chinese Academy of Sciences http://madrigal.iggcas.ac.cn/madrigal
- HAO/NCAR http://madrigal.hao.ucar.edu
Users who wish to access the empirical model source code stored on the CEDAR Data System or small ascii 'protected' data sets should use the "Protected" data link described below.
CEDAR Data Services (VSTO and Protected ascii files)
The CEDAR Data System (formerly the CEDAR Database and before that, the Incoherent Scatter Radar Database) was a cooperative project between the High Altitude Observatory (HAO) division of the National Center for Atmospheric Research (NCAR), the National Science Foundation (NSF), and numerous institutions that provide upper atmosphere data and model output for community use. Except for the "Protected Ascii Files", all the functions and data of the CEDAR Database have been taken over by the CEDAR Madrigal Archive at http://cedar.openmadrigal.org.
The CEDAR Data System mission is to provide: (1) a long term archive for observations and models of the Earth's upper atmosphere and geophysical indices and parameters needed to interpret them, (2) browsing capability to survey the data holdings and identify periods, instruments, models, of interest, (3) reliable data access methods that are fast, stable and interactive, and (4) detailed documentation on data acquisition and reduction.
The data is located both in the CEDAR Madrigal Archive and in the Virtual Solar Terrestrial Observatory (VSTO) linked below.
