Scientific paper

A new technique is presented to estimate electric fields and currents in a localized region of the high-latitude ionosphere by combining two magnetogram-inversion algorithms. This paper describes the concept and practical procedures of the method as well as the first results of our efforts in which this new scheme is applied to northern Scandinavia, computing the ionospheric parameters on a small scale. Examining latitudinal profiles of these parameters and precipitating particles, it is found that the region of the most intense precipitation in the morning sector is located equatorward of the region of the strongest electric field. To evaluate the relative importance of ionospheric and magnetospheric effects, the field-aligned current is divided into two components: (del Sigma) dot E and Sigma del dot E. These two components give often the opposite directions in the resultant field-aligned currents. The relative strength of the two components appears to vary considerably with latitude.
