Can the tardigrade Hypsibius dujardini survive in the absence of the geomagnetic field? [PDF]
PLoS ONE, 2017 Earth's geomagnetic field has undergone critical changes in the past. Studies on the influence of the magnetic field on Earth's organisms are crucial for the understanding of evolution of life on Earth and astrobiological considerations. Numerous studies

Datasets of the solar quiet (Sq) and solar disturbed (SD) variations of the geomagnetic field from the mid latitudinal Magnetic Observatory of Coimbra (Portugal) obtained by different methods [PDF]
Data in Brief, 2021 The datasets of daily variations is obtained from the geomagnetic field raw observations at the Coimbra Magnetic Observatory (COI, Portugal). The data set was obtained for the 01.01.2007-31.12.2017 time interval and covers almost the entire solar cycle ...

Geomagnetic field shielding over the last one hundred thousand years
Journal of Space Weather and Space Climate, 2022 The geomagnetic field prevents energetic particles, such as galactic cosmic rays, from directly interacting with the Earth’s atmosphere. The geomagnetic field is not static but constantly changing, and over the last 100,000 years, several geomagnetic ...

Solar flares and variation of local geomagnetic field: Measurements by the Huancayo Observatory over 2001-2010 [PDF]
Serbian Astronomical Journal, 2017 We study the local variation of the geomagnetic field measured by the Huancayo Geomagnetic Observatory, Peru, during 2001-2010. Initially, we sought to relate the SFI values, stored daily in the NOAA's National Geophysical Data Center, with the ...

Changes in cosmic ray cut-off rigidities due to secular variations of the geomagnetic field [PDF]
Annales Geophysicae, 1997 An analytical expression is derived for the cutoff rigidity of cosmic rays arriving at a point in an arbitrary direction, when the main geomagnetic field is approximated by that of an eccentric dipole.
