International Geomagnetic Reference Field: the thirteenth generation
Overview
Paper Summary
The thirteenth generation of the International Geomagnetic Reference Field (IGRF-13) provides updated models of Earth's main magnetic field for epochs 2015.0 and 2020.0, along with a predictive secular variation model for 2020.0-2025.0. The model reveals continued weakening of the dipole moment and westward drift of the South Atlantic Anomaly, with significant implications for navigation, satellite operations, and studies of Earth's core and magnetosphere.
Explain Like I'm Five
Scientists made a new map of Earth's invisible magnetic shield. They found it's getting a little weaker and changing shape, which is important for things like compasses and satellites in space.
