Earth Magnetic Field Models
Data based magnetic field models provide descriptions of the geomagnetic field and its evolution for each location on Earth and are used to study the underlying processes. We develop and contribute to global and regional models of the Earth’s internal magnetic field. These include core field models for recent and long time scales based on observational or paleomagnetic data and lithospheric field models using satellite, aeromagnetic and ground data.
ArchKalmag14k - Correlation based model of the holocene core field, based on archeomagnetic and volcanic data
Correlation based geomagnetic field model of the holocene core field, based on archeomagnetic and volcanic data. ArchKalmag14k is constructed using methods from Bayesian statistics, in particular Gaussian processes and the Kalman filter, to reflect …
CALSxk (10.000 - 3.000 years BP) - Geomagnetic field model for the period 10.000 - 3.000 years BP
Geomagnetic field models of the last 3 to 10 kyrs based on archeo- and paleomagnetic data. This updated version of geomagnetic field description for the past 10 000 years is mainly based on the same data as CALS10k.1b. However, the model offers high…
GGF100k - Model that covers the past 100.000 years and it is the longest global reconstruction of the geomagnetic field
GGF100k is a global geomagnetic field model covering the past 100,000 years. It is the first model that provides a global view of the geomagnetic field evolution over an extended period. The model is based on an extensive global dataset of over 100 …
