Накратко на български

Връзката между магнитосферата и йоносферата се анализира чрез проучване на атмосферните гравитационни вълни и смущенията в плазмата. Това помага за по-доброто разбиране на физичните процеси в горните слоеве на атмосферата и влиянието на геомагнитната активност върху тях.

Magnetosphere-Ionosphere Coupling and Associated Wave Activity

The project aims to contribute to the understanding of auroral AGWs/TIDs, by providing a better description of their characteristics and variability, as well as investigating the possible link to geomagnetic activity. The project is expected to make a strong impact in the areas of space and atmospheric science: physics of AGWs and TIDs, magnetosphere-ionosphere coupling, data processing and analysis techniques and numerical modelling of the thermosphere-ionosphere. The project has three major objectives: O1: Determine the spectral characteristics of the AGW / TID activity, including their temporal and altitude variations, using plasma frequency and ionospheric tilt measurements. O2: Determine the statistical distribution of propagation parameters (vertical and horizontal wavelength, phase speed, propagation direction), while also studying their temporal and altitude variation. O3: Investigate possible correlations between parameters describing AGW / TID activity and indices describing the level of geomagnetic activity (Kp and Ap index), both during periods of increased geomagnetic activity. All three objectives have been successfully achieved, the project having produced a repository of data and a catalogue describing TID activity at Tromso for a 7-year period between 2012-2018, available on the project website. Additionally, a significant geophysical result was achieved in demonstrating in a statistical sense the correlation between geomagnetic activity and the level of ionospheric variability over a large time interval under mostly quiet geomagnetic conditions.

Цел на проекта

This project will study a class of atmospheric waves (known as atmospheric gravity waves) and associated travelling ionospheric disturbances at high latitudes, along with the possible connections between this wave activity and geomagnetic activity. The project will use data obtained using the Tromso Dynasonde (electron density and ionospheric tilts) between January 2014 and December 2016. The project will fully investigate the spectral characteristics of the data, along with the statistical distribution of the propagation parameters, and their altitude and temporal variability. The final goal is to identify possible correlations between these parameters and indicators of the level of geomagnetic activity. The project is submitted by a researcher with substantial experience in the subject areas, originally gained in during his PhD studies at the University of Colorado. The applicant is seeking the fellowship to aid in his reintegration at the Institute of Space Science in Romania.
