POMME-10

The Potsdam Magnetic Model of the Earth (POMME) is a research model that describes both the internal and the external (magnetospheric) fields, taking into account the variability of space weather.

EMAG2-v3

The Earth Magnetic Anomaly Grid: 2 Arc-Minute Resolution (EMAG2), version 3, is a grid of crustal anomalies reported in two forms: a consistent 4km upward-continued grid and an anomaly at sea level above oceanic regions and 4km altitude above continental regions.

EMM2017

The Enhanced Magnetic Model 2017 (EMM2017) is a degree and order 790 internal field model, resolving magnetic anomalies as short as 51 km wavelength.

WMM2020

The World Magnetic Model 2020 (WMM2020) is a core field model with degree and order 12, based on satellite observations, and forecasting the geomagnetic field through December 31, 2024. The WMM is the standard model used for navigation, attitude, and heading referencing systems that rely on the geomagnetic field.

IGRF-13

The International Geomagnetic Reference Field (IGRF), 13th generation, is a model that describes the core field from 1900 to 2025. It was developed by an international team of scientists, under the auspices of the International Association of Geomagnetism and Aeronomy (IAGA).

DIFI-7

The Dedicated Ionospheric Field Inversion (DIFI) model is a Swarm-based, global model of the Sq and equatorial electrojet magnetic fields at mid- and low latitudes. It describes variations in local time, season, and solar flux, and separates primary and induced magnetic fields.

HDGM2023 and HDGM2023-RT

The High Definition Geomagnetic Model 2023 (HDGM2023) is a global, high-resolution model (degree 790) of the Earth's geomagnetic main and crustal fields, providing magnetic field values (total field, dip, and declination) at any point above or below the Earth's surface for the year 2023. An optional extension to the HDGM is the HDGM-RT, which provides near real-time estimates of the external disturbance field caused by the solar wind and includes a magnetic field model for daily variations due to ionospheric current systems.
