Fig. 9

Power spectra at the Earth’s surface of the DTU candidate models for IGRF-12 (i) DGRF candidate for the MF in epoch 2010.0 (black line with circles), (ii) IGRF candidate for the MF in epoch 2015.0 (black line with squares) and (iii) candidate for the predicted linear SV 2015–2020 (black line with diamonds). Also shown is the average annual change between the DTU MF candidate models in 2010.0 and 2015.0 (black dashed line with crosses) as well as the IGRF-11 MF model for epoch 2010.0 and the IGRF-11 predicted SV 2010.0–2015.0 (both red lines)
