Measurement results of the electric fields in cloud-to-ground lightning in nearby Munich, Germany

This report gives an overview of the electric fields measured in cloud-to-ground lightning in nearby Munich, Germany between 1984 and 1993. The electric fields and their derivatives during the onset of return strokes were recorded with three different measuring systems during three measuring periods. The statistical results include the initial peaks of the return-stroke field as well as the maximum values and the full widths on half maximum of their derivatives. Based on the measured fields of multiple-stroke flashes and negative flashes containing continuing currents statistics about the interstroke intervals, the numbers of return strokes and the duration of continuing currents are presented.
