Physics-based secular variation candidate models for the IGRF [PDF]
Earth, Planets and Space, 2021 Each International Geomagnetic Reference Field (IGRF) model released under the auspices of the International Association of Geomagnetism and Aeronomy comprises a secular variation component that describes the evolution of the main magnetic field ...

The Kalmag model as a candidate for IGRF-13 [PDF]
Earth, Planets and Space, 2020 We present a new model of the geomagnetic field spanning the last 20 years and called Kalmag. Deriving from the assimilation of CHAMP and Swarm vector field measurements, it separates the different contributions to the observable field through ...

Secular variations of geomagnetic declination in the Karadag point and the global helio-geodynamic processes [PDF]
Геофизический журнал, 2019 To study the changes in the local variations of geomagnetic field, the Karadag point was chosen due to the fact that we found previously on increased insolation and the surface temperature of the earth at this point over the last century (compared to ...

IGRF candidates for 1980 and 1985 [PDF]
Physics of the Earth and Planetary Interiors, 1987 Abstract A tenth degree and order spherical harmonic model of the main geomagnetic field for 1980 has been derived using MAGSAT data supplemented by aeromagnetic vector data collected by the Project MAGNET aircraft. A secular variation model of degree and order 8 for 1982.5 based on magnetic observatory and repeat station measurements has also been ...

Determination of the IGRF 2000 model [PDF]
Earth, Planets and Space, 2014 The IGRF 2000 has been estimated from magnetic measurements taken by the Orsted sattelite in summer 1999. For this purpose, three models have been derived: The first two models were estimated using a few geomagnetic quiet days in May and September 1999, respectively.
