We are indebted to the Director and staff of EISCAT for operating the facility and supplying the data. EISCAT is an international association supported by Finland (SA, Suomen Akatemia), France (CNRS, Centre National de la Recherche Scientifique), Germany (MPG, Max-Planck-Gesellschaft), Japan (NIPR, National Institute for Polar Research), Norway (NFR, Norges forskningsrad), Sweden (NFR, Naturvetenskapliga forskningsradet) and the United Kingdom (PPARC, Particle Physics and Astronomy Research Council).

Instrument/Model Description

The EISCAT (European Incoherent SCATter) Svalbard Radar (ESR) consists of a transmitter and receiver in Longyearbyen, Norway (78.15N, 16.04E; 75.0 magnetic N). Observations were begun in 1996. The system was added to the EISCAT KST (Kiruna/Sodankyla/Tromso) tri-static facility in Scandinavia, which has its own web page.

There are several common programs used for the World Days, which are a part of the CEDAR Database from the KST site, but not yet on a regular basis from the ESR site. There are many other experimental times which should be accessed with the aid of an EISCAT colleague.

The power profiles are calibrated with an on-site ionosonde, and are then corrected for Te and Ti effects which are deduced from the auto-correlation functions (ACFs). The collision frequency model used is the CIRA 1972 model atmosphere in Banks and Kockarts (1973), in Aeronmy Part A. The NO+ composition is assumed zero above 300 km.

There are 4 areas in the summary plots for image plots as a function of height and time of the electron density, electron temperature, ion temperature, and either the line-of-sight velocity, or line plots of the perpendicular and parallel ion velocities closest to 300 km. The image plots are binned in 45 minutes and 40 km, except for the uncorrected electron densities, which are binned at 10 km. The data are averaged above 60 degrees of elevation. There are 2 days per page. Summary plots of the EISCAT are also available for these and other days at

Summary Plots

Not all the electron densities are plotted if the experiment changed during the 2 day period plotted, but it exists in some form.
