Electrical currents circulating within the fluid outer core of the Earth are responsible for the main magnetic field of our planet. Numerical simulations of the geodynamo have been employed to elucidate its mechanism. They can also produce synthetic data (magnetic field and fluid velocity at the core surface, angular momentum of the core), which ha...
Cette thèse explore la dynamique du noyau terrestre en analysant les champs gravimétriques et magnétiques. Les mouvements convectifs du noyau fluide, générant le champ magnétique, subissent des perturbations, provoquant des variations de densité et de pression qui entraînent des variations du champ de gravité. Ce travail approfondit l'observabilité...

In this paper numerical simulations of the Earth’s magnetic field in the south-eastern part of an Najaf-Karbala Plateau and to the north of the centre of An-Najaf governorate have been investigated using the WMM2015 model. The study area is located at (Latitude = 32.3180°-31.99°) N, (Longitude = 44.5160°-44.0690°) E, and ranging altitude between 20...

Two different types of magnetometer, the Proton Precession Magnetometer (PPM) and the Shipboard Three-Component Magnetometer (STCM), each possess its own strengths and weaknesses in their operation. The PPM can measure the total intensity of the Earth's geomagnetic field without requiring complicated post-processing and correction. However, its ope...
Living organisms have evolved within the natural electromagnetic fields (EMFs) of the earth which comprise the global atmospheric electrical circuit, Schumann resonances (SRs) and the geomagnetic field. Research suggests that the circadian rhythm, which controls several physiological functions in the human body, can be influenced by light but also ...

Thesis (M.Sc.) -- İstanbul Technical University, Graduate School, 2023 / The phrase "space weather" is used to describe the conditions in space, more specifically in the solar system. Space weather is concentrated on the Sun since it is the solar system's primary energy source. The Sun's highly dynamic structure results in energy bursts that can ta...

We analyzed the applicability of the principal component analysis (PCA) as a tool to extract the Sq variation of the geomagnetic field (GMF) taking into account different geomagnetic field components, data measured at different levels of the solar and geomagnetic activity, data from different months. The validation of the method was performed with ...
The geomagnetic field on the core-mantle boundary (CMB) is characterized by weak or even reversed field in the polar regions and intense flux patches at the edges of the intersection of the inner-core tangent cylinder (TC) with the CMB. This high-latitude field morphology is in agreement with thermal wind theory inside the TC in which polar upwelli...

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 excursions occurred. During geomagnetic field excursions, the field strength is significantly decre...
