Long Period European Geomagnetic Secular Variation Confirmed [PDF]
Geophysical Journal International, 1975 Summary The periodicity of geomagnetic secular declination changes for the last 10 000 yr, first observed from sediments in Lake Windermere, is verified by radiocarbon age determinations from Blelham and Ennerdale lakes in north-west England. No clear correlation of the British records can be made with Continental European data, suggesting that a ...

Data use investigation for the magnetic field satellite (MAGSAT) mission: Geomagnetic field forecasting and fluid dynamics of the core [PDF]
MAGSAT data were used to construct a variety of spherical harmonic models of the main geomagnetic field emanating from Earth's liquid core at poch 1980. These models were used to: (1) accurately determine the radius of Earth's core by a magnetic method, (

Geomagnetic effects on cosmic ray propagation under different conditions for Buenos Aires and Marambio, Argentina [PDF]
, 2014 The geomagnetic field (Bgeo) sets a lower cutoff rigidity (Rc) to the entry of cosmic particles to Earth which depends on the geomagnetic activity. From numerical simulations of the trajectory of a proton using different models for Bgeo (performed with ...

Some new methods in geomagnetic field modeling applied to the 1960 - 1980 epoch [PDF]
The utilization of satellite and surface data together permitted the incorporation of a solution for the anomaly field at each observatory. The residuals of the observatory measurements to such models is commensurate with the actual measurment accuracy ...
