1. Interference in Global Positioning System Signals and its Effect on Positioning and Remote Sensing
Sammanfattning : GPS and the other GNSS systems (GLONASS, Galileo and Beidou-2/COMPASS) is used to position billions of devices and is saving lives, the environment and money on a daily basis. GNSS enables anyone to determine their own unique global location. LÄS MER
2. Improved data analysis methods for the millimetre-wave observation of strato-mesospheric ozone and winds over Northern Sweden
Sammanfattning : This thesis analyses and discusses the work done to improve an ozone retrieval method. The newly implemented method aims to invert emission spectra measured with the millimetre-wave radiometers KIMRA and MIRA2 at the Swedish Institute of Space Physics (IRF) in Kiruna. LÄS MER
3. Atmospheric Species and Spectral Radiation in Terrestrial Exoplanets : Implications for Astrobiology
Sammanfattning : The physical properties of the planets and their parent stars are fundamental in the composition of atmospheres and radiative environments, which fundamentally determine their surface temperature and habitability. The atmospheric composition and radiation play a vital role in the emergence of life. LÄS MER
4. Modeling the Zeeman Effect in Planetary Atmospheric Radiative Transfer
Sammanfattning : There are special effects in spectroscopy that must be considered in order to fullyexplain how molecular oxygen interacts with radiation in planetary atmospheres.One of these, the Zeeman effect, is described in this thesis. LÄS MER
5. Modeling the Zeeman Effect in Planetary Radiative Transfer and Applications
Sammanfattning : Remote sensing is about retrieving distant physical properties from locally observed radiation. The first step to remote sensing is to describe, or model, the radiative transfer. LÄS MER
