Abstract:

Ionospheric parameters obtained by the Chatanika radar during the ICECAP 73 launches are presented and discussed. For each of the four launch days considered 21, 22, 24, and 27 March 1973, the radar results have been compared and found consistent with measurements made with other sensors operating in support of ICECAP. Joule heating is found to be an important part of the auroral energy budget. The ratio of joule heating to particle energy flux obtained from photometric measurements range from a high of 0.67 on the 22 March 1973 launch to a low of 0.52 on the 27 March 1973 launch. Particle energy flux estimated from radar data is found to agree to within a factor of 2 with photometric results. During cloudy periods when optical observations cannot be made, the radar can provide backup to this type of measurements. Author
