Earth's Magnetic Makeover: New and Improved IGRF-13 is Here!
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.
Possible Conflicts of Interest
None identified
Identified Weaknesses
Lack of Novel Scientific Findings
The paper's focus is on providing an updated model (IGRF-13) and its coefficients, rather than presenting new scientific findings or analyses. It serves primarily as a reference for those who utilize the IGRF for various applications.
Limited Methodological Detail
The paper mentions the use of data from various satellite missions and observatories, but lacks a detailed description of the data processing and validation methods employed. This makes it difficult to assess the quality and reliability of the resulting model.
Lack of Uncertainty Quantification
While the paper acknowledges uncertainties in IGRF models, it doesn't offer a comprehensive assessment of the uncertainties associated with IGRF-13 specifically. Quantifying these uncertainties is crucial for users to interpret the model outputs accurately.
Rating Explanation
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.
