Abstract

In this paper we recursively estimate the magnetic and electric potential of the EarthÂ¿s Arctic region. We construct estimates based on data gathered from over 85 magnetometer sources and several radar sites dispersed around the North Pole. The approach to estimating the Arctic polar cap electric potential is through data assimilation based on linear and nonlinear Kalman filters. We demonstrate that the magnetic and electric potential over the Arctic region can be approximately reconstructed from sparse, nonuniform magnetometer and radar data sources.
