A possible effect of atmospheric circulation in the daily variation of the earth's magnetic field. II. [PDF]

open access: yes, 1965
Seasonal features that are not related in a simple way to solar declination occur in the daily variation of the horizontal intensity of the earth's magnetic field at Tucson, as at Honolulu studied previously.

Magnetic Declination and Space Weather: A possible mechanism in Climate Change and Weather Forecast [PDF]

open access: yesE3S Web of Conferences
Numerous studies have been published on the contribution of Earth’s magnetic field to Earth’s climate. Most of them are being focused on the upper atmosphere and the caused effects in the conductivity of the ionosphere, the transport processes of ...

A modelling study of the latitudinal variations in the nighttime plasma temperatures of the equatorial topside ionosphere during northern winter at solar maximum [PDF]

open access: yesAnnales Geophysicae, 2000
Latitudinal variations in the nighttime plasma temperatures of the equatorial topside ionosphere during northern winter at solar maximum have been examined by using values modelled by SUPIM (Sheffield University Plasmasphere Ionosphere Model) and ...

The Dipole Anisotropy of Galactic Cosmic Rays [PDF]

open access: yes, 2018
The arrival directions of Galactic cosmic rays exhibit anisotropies up to the level of one per-mille over various angular scales. Recent observations of TeV-PeV cosmic rays show that the dipole anisotropy has a strong energy dependence with a phase-flip ...

Report on the magnetic survey in Slovakia for the 2014.5 epoch

open access: yesContributions to Geophysics and Geodesy, 2016
The models of the distribution of the elements of the geomagnetic field must be updated regularly. For this purpose geomagnetic measurements have to be carried out repeatedly at geomagnetic observatories as well as at temporary observation points.

A Study on anisotropy of cosmic ray distribution with a small array of water-cherenkov detectors [PDF]

open access: yes, 2007
The study of the anisotropy of the arrival directions is an essential tool to investigate the origin and propagation of cosmic rays primaries. A simple way of recording many cosmic rays is to record coincidences between a number of detectors.

Model magnetne deklinacije za Slovenijo ; The model of magnetic declination of Slovenia [PDF]

open access: yesGeodetski Vestnik, 2012
Predstavljen je polinomski model magnetne deklinacije za območje Slovenije, ki zaradi svojega lokalnega značaja omogoča točnejše izračunavanje deklinacije, kot je to mogoče s svetovnimi modeli. Podlaga za izračun koeficientov modela so vrednosti magnetne

The development of a Utopian city? Comparing land-and skyscapes in Santa Cruz de Tenerife and San Cristobal de la Laguna [PDF]

open access: yes, 2018
We discuss the peculiar planning of the city of San Cristóbal de La Laguna, in the Canary Island of Tenerife (Spain), when compared to the nearby and essentially contemporary Santa Cruz de Tenerife, which served as a maritime port of the former city. For
