Improving Earth’s Magnetic Field Measurements by Numerical Corrections of Thermal Drifts and Man-Made Disturbances

Figure 8

Comparison of aligned BDV and PLM magnetometer readings (the mean is removed to show only Earth’s field variations) during three days in July 2017. The difference is well below 5 nT during the observed 14°C ambient temperature swing. The divergences near the dataset end were caused by false temperature readings.
