What is New in the CEDAR Database?

New Data Sets, Updates, and In-Progress:

These new data sets and updates were added to the CEDAR Database in July 2001 or later, and highlight the time of the TIMED-CEDAR satellite, which was put into orbit in December 2001. Most summary (survey, quick-look) plots are completed (but not all!), and the links below go to the descriptive summary browse pages for the data sets.

The data are available via Data Services - 'Get/Plot Data' or 'Browse Inventory'

  • Storms for Sun-Earth Connection virtual conference and other storms
  • Satellite Auroral Indices (up to 2007)
  • 2007 Data
  • 2006 Data
  • 2005 Data
  • 2004 Data

  • 2003 Data
  • 2002 Data
  • Pre 2002 Data

  • Other Completely New Instruments (Mostly Pre 2002 data):

  • Regular Updates (2002 and later):
  • Pre 2002 Data

  • Other Data Sets In-Progress:


    Statistics of Use:

    The statistics for 2002-2003 show an increase in the number of users, especially for indices (IND), empirical models (EMP), red-line FPIs (FPI), optical instruments below 150 km (OHP), lidars and MLT radars. There are also double the number of new users and a jump in the number of instruments used. This follows from the fact that the TIMED satellite, operational in January 2002, emphasizes the middle atmosphere. By the end of 2002, the CEDAR DB TIMED data sets for 2002 data were in FPI, ISR, LID, MLT and OHP. For IS Radars (ISRs), there are a few more users, most notably for Jicamarca data at the magnetic equator.

    The server was changed in late June of 2004, and statistics are missing between 26 June and 15 Sep for all instruments, and up to 5 Oct for empirical models. The 2006 yearly statistics cover up to 13 Oct. The number of foreign requests for webnames is increasing.

    About two thirds of the instrument requests are for IS Radars, but about half of the instrument users ask for other instruments.

    Web Access Methods:

    The web access using URL and inventory list methods is available and now also includes the ability to plot certain sets of data.
