Construction of a Spatiotemporal Model of the Main Geomagnetic Field from Satellite Data for the 2015–2020 Epoch
摘要
Abstract
A model of the main geomagnetic field for 2020 and a model of secular field variations up to 2025 have been constructed from measurements from SWARM satellites. These models have been included in International Geomagnetic Reference Field model IGRF-13. The methodology for data selection and model calculation is described.
