Whistler Waves Detection - Investigation of modern machine learning techniques to detect and characterise whistler waves
… the estimation of electron density in the plasmasphere region of the magnetosphere. Therefore the identification and characterisation of whistlers are important tasks to monitor the plasmasphere in real time and to build large databases of events to be used for statistical studies. The …

A study of the plasmaspheric electron content using satellites of the global positioning system
… and protonosphere together comprise the plasmasphere. The ionisation along a ray-path (defined by the elevation and azimuth angles from a point on the Earth's surface) is measured in terms of the number of free electrons occupying a column of unit area along that ray-path: the total …

Empirical Study of Subauroral Polarization Streams (SAPS) through Decades of Satellite Observations
… the effects of SAPS on the thermosphere and plasmasphere.

A Dynamic Coupled Magnetosphere-Ionosphere-Ring Current Model
… averaged plasma-beta <=1, the use of a plasmasphere model, and the MIX ionosphere model. Compared to stand-alone MHD, the coupled model produces a substantial increase in ring current pressure and reduction of the magnetic field near the Earth. In the ionosphere, stronger region-1 and …

High-latitude coupling processes between thermospheric circulation and solar wind driven magnetospheric currents and plasma convection
… model describes the thermosphere, ionosphere, plasmasphere and inner magnetosphere as well as the electrodynamics of the coupled MIT system for the altitudinal range from 80 (60) km up to the 15 Earth radii. In the present study, I developed and investigated several variants of the …

Remote sensing of ion-neutral charge exchange and diffusive transport in planetary atmospheres
… of diurnal variability of the ionosphere and plasmasphere, the ionized regions of the Earth’s upper atmosphere, and also indicate over- estimation of [H] by the widely used neutral atmosphere model, MSIS00. Furthermore, this thesis presents a novel parametric technique to quantify the …

Ultra-Low Frequency Waves at Middle Latitudes During Substorms: Observations and Modeling
… observations confirm that during substorms the plasmasphere can be strongly eroded away and the plasmapause moves to middle latitudes.</p> <p>The model uses the observed frequency of 1.1 mHz to drive the surface waves on the plasmasphere. The simulations show that the large scale electric field …

Extreme Ultraviolet Airglow Observations and Applications from the Ionospheric Connection Explorer
As humanity continues its expansion into space, the understanding of the near-Earth space environment has never been more critical. As the ionosphere and thermosphere form the boundary between Earth's atmosphere and outer space, characterization of these regions is critical to understanding …

Vliv změny parametrů termálního plazmatu Země a slunečních indexů na úmrtnost podle příčin v České republice
Cílem diplomové práce bylo hledání závislosti intenzity úmrtnosti v České republice podle vybraných příčin úmrtí na sluneční aktivitě během vzestupné a sestupné fáze slunečního cyklu v období 1994-2011, a to použitím metod statistické analýzy mnohorozměrných dat. Sluneční aktivita byla …
