1. Studies of Atmospheric Water Vapor Using the Global Positioning System
Sammanfattning : Atmospheric water vapor is of fundamental interest in the Global Positioning System (GPS) and Very Long Baseline Interferometry (VLBI) techniques. These techniques are based on the timing of radio waves propagating through the atmosphere. LÄS MER
2. Representation and diurnal variation of upper tropospheric humidity in observations and models
Sammanfattning : The role of water vapour is manifold in its climate regulation of the Earth system. Most important of all despite its low concentration, is the role it plays in the upper troposphere. LÄS MER
3. Satellite and radiosonde measurements of atmospheric humidity
Sammanfattning : This licentiate thesis is based on two papers which are related to the study ofatmospheric humidity. The first paper mainly focuses on a non linear method forretrieving atmospheric humidity from infrared sounder satellite measurements basedon fuzzy clustering which could potentially improve the retrieval accuracy. LÄS MER
4. Measuring and modelling variations in the distribution of atmospheric water vapour using GPS
Sammanfattning : Turbulence introduce variations in the refractive index of air, which in turn result in fluctuations in the phase and amplitude of radio signals propagating through the atmosphere. Most important are the variations due to fluctuations in the water vapour field. LÄS MER
