CONVERSION OF TOPSIDE lONOGRAMS TO EXPONENTIAL ELECTRON-DENSITY PROFILES

摘要

Ion grams obtained from the Alouette Satellite suggest that above the F2 layer the electron-density profile is an exponential or quasi-exponential function. This concept of electron distribution is used in reducing the ion grams to true-height profiles. The reduction yields the distribution as well as the altitude variation of the exponential function.
