International Geomagnetic Reference Field: the thirteenth generation
Descripción general
Resumen del artículo
This paper introduces IGRF-13, the thirteenth generation of the International Geomagnetic Reference Field, providing updated coefficients and maps for the Earth's main magnetic field. The model includes a definitive main field for 2015.0, a main field for 2020.0, and a predictive secular variation model for 2020.0-2025.0, indicating continued weakening of the dipole moment and westward movement of the South Atlantic Anomaly.

Scientists made a new map of Earth's invisible shield, its magnetic field. They found it's moving a little, like a wobbly compass, and getting a tiny bit weaker in some places.

Explicación de la calificación
This paper provides a valuable update to a widely used geomagnetic reference model, benefiting numerous applications in various fields. Although it doesn't present groundbreaking research, its meticulous documentation of the model and coefficients serves as a significant contribution. The limited methodological detail and lack of specific uncertainty quantification are minor drawbacks.
