global magnetic models

Global magnetic models are detailed representations of Earth's magnetic field, created by scientists using measurements from satellites and ground stations. These models help us understand how the magnetic field varies across different regions and over time. They are essential for navigation systems, understanding geophysical processes, and protecting technologies from magnetic disturbances. Essentially, they provide a comprehensive map of Earth's magnetic environment, capturing both the permanent components and the dynamic changes caused by Earth's interior and external influences like solar activity.
