CEDARWEB Tools and Empirical Models

There are many tools, e.g. computer codes and lists, available to assist in using the extensive data available from the CEDAR Data System. If you have such a tool you'd like to make available, please contact us. In addition, solar wind structure designations and source code for a number of empirical models are made available to enhance use of the CEDAR database.

The tools and models are grouped as follows:

• Analysis codes (includes some plotting)
  • KLidarPhotons2Density.pro is the IDL code written by Jonathan Friedman of Arecibo Observatory to convert photon counts to potassium [K] density. This is also available above as a 'notepad' or other text file.
• Empirical Models and links to newer versions (plus links to large time-dependent models)
• Various small data sets in text format (not in the regular CEDAR DB in binary format)
  • DMSP satellite estimates of Hemispheric Power and the Auroral Boundary Index (the equatorward boundary of the aurora at 0000 MLT)
  • Solar Wind Structure lists from 1963
  • Neutral Mass Density from satellite drag studies by Emmert from 1967 at 250, 400, and 550 km
  • CSU sodium lidar nightly average Tn (70-119km) from March 1990 to March 2010
• Lists of Instruments
• Lists of Parameters
• Codes to plot data (local and remote access)
• Codes to read data (local and remote access) and link to examples of how to access the data on the DB
• Tools for serving CEDAR DB at your site
