Fig. 8From: Comparison of global geomagnetic field models and evaluation using marine datasets in the north-eastern Atlantic Ocean and western Mediterranean SeaMaps of differences between global anomaly models and marine data for the NEAWM area. a Intensity values of the anomaly field (ANO) estimated from HDGM2016 model up to SH degree 720 for the date 01/01/2015 (grid spacing: 0.5°) versus processed and filtered data. b WDMAM anomaly grid (grid spacing: 3 arc min.) versus unfiltered data. Images are derived from 2 min.-gridded models of differences computed between models and data. TMR Tore-Madeira RiseBack to article page
