Modelling earth's magnetic field over southern Africa between 2014 and 2023 applying revised spherical cap harmonic analysis (R-SCHA) on Swarm satellite and ground-based data
Puntos clave
Earth's magnetic field variations were assessed over Southern Africa from 2014 to 2023 using advanced techniques.
Incorporating satellite data from the Swarm mission alongside ground-based observations led to improved accuracy.
Spherical cap harmonic analysis was employed to enhance the modeling of geomagnetic anomalies in the region.
The findings suggest ongoing changes in Earth's magnetic field, indicating the need for updated geomagnetic models.
