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…
Declination Calculator for the International Geomagnetic Reference Field IGRF

The declination calculator provides declination values for any location on Earth and any time between 1900 and 2025. The calculation is based on the International Geomagentic Reference Field (IGRF) which describes the geomagnetic core field. The cal…
GEOMAGIA50 – Paleomagnetic and Chronological Data for the Past 50 Ka

The GEOMAGIA50 database is an international collaboration to provide easy access to published archeomagnetic/volcanic and sediment paleomagnetic and chronological data for the past 50,000 years. GEOMAGIA50 has been funded by the US National Science …
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 …
GGFSS70 - Geomagnetic model that covers the period of 70 - 15 kyrs, that includes 3 geomagnetic excursions

The GGFSS70 is a global geomagnetic field model covering the period 70,000 to 15,000 years ago. The model is based on nine selected sediment records from globally distributed sites. The dataset contains only high-quality paleomagnetic records, with …
Geomagnetic Hpo Index

The geomagnetic Hpo index is a Kp-like index with a time resolution of half an hour, called Hp30, and one hour, called Hp60. besides that, the Hpo index is not capped at 9 like Kp, but is an open ended index that describes the strongest geomagnetic …
Geomagnetic Kp index

The Indices of Global Geomagnetic Activity is a service contributing to the International Service of Geomagnetic Indices (ISGI) of the International Association of Geomagnetism and Aeronomy (IAGA) provided by the GFZ Helmholtz Centre for Geosciences…
INTERMAGNET

INTERMAGNET is an international program to provide quality controlled geomagnetic observatory data through a website and an ftp-server. Both archive and near-real time data are provided. The INTERMAGNET observatories in Niemegk, Wingst, Tristan da C…
LSMOD Models - Models for the periode of 30 to 50 kyrs that contain the Laschamp and Mono Lake field excursions

Geomagnetic field models for the periode of 30 to 50 kyrs that contain the Laschamp and Mono Lake field excursions. The LSMOD models (current version LSMOD.2) represent the global evolution of the geomagnetic field for the time interval 50 to 30 ka.…
Mag.num - Model of the geomagnetic core field, based on satellite and observatory data

Mag.num models are the series of recent GFZ high-precision geomagnetic core field models that rely on satellite magnetic field measurements, in particular on calibrated Swarm and CHAMP vector field and ground observatory data. The coefficients of th…
Magnetic Satellite Data Products

The GFZ section "Geomagnetism" provide data products derived from the measurements of the ESA (European Space Agency) missions for Earth Observation (EO), e.g., Swarm as well as for German missions, e.g., CHAMP (CHAllenging Minisatellite Payload). O…
