Fig. 4From: Tide-induced magnetic signals and their errors derived from CHAMP and Swarm satellite magnetometer observationsStandard deviation of posterior errors of the tidal radial magnetic fields as estimated by the KALMAG Kalman filter. Left column: M2, S2, K1, N2. Right column: O1, K2, P1, Q1. All fields are represented at the satellite height of 430 km above sea level. Please note the different color bar rangesBack to article page
