Abstract:

Monitoring the total electron content of the ionosphere by recording the Faraday rotation of radio signals from geostationary satellite is a powerful tool to study the temporal variations of the ionosphere. Using an auroral zone station like Norssarssuaq, it is possible to study the very irregular region which is seen during night time north of the trough of the ionosphere. A connection of night time increases of the electron content and substorm activity is discussed. The data reduction of the Faraday rotation is described in detail. A method is given for solving the n-pi ambiguity and for determining the temperature of the neutral atmosphere.
