The algorithm developed by Kamide et al. (1981) has been extensively used in estimating ionospheric electric fields, ionospheric currents, and field-aligned currents over the entire polar region from ground magnetic chain data with a time resolution of about 5 min. However, in the considered algorithm and some other similar methods, geomagnetic field lines are assumed to be effectively radial, so that it is important to estimate errors resulting from such an assumption. In this paper, an iteration scheme is developed in which realistic curved geomagnetic field lines are employed. Both the ionospheric and field-aligned currents have been reestimated, and it was found that the correction to the ionospheric currents and the field-aligned currents obtained from the Kamide-Richmond-Matsushita scheme is 5-20 percent in the high-altitude (60 deg - 80 deg) region and is 15-35 deg in the middle latitude (less than 60 deg) region.
