Fig. 3From: Tide-induced magnetic signals and their errors derived from CHAMP and Swarm satellite magnetometer observationsTidal radial magnetic field (M2). Left column: results from CIY4 (Sabaka et al. 2018), i.e., 4 years of Swarm data. Right column: results from CM5 (Sabaka et al. 2015), i.e., mostly 12 years of CHAMP data. All fields are represented at the satellite height of 430 km above sea levelBack to article page
