1. Ground based measurements of upper atmospheric CO and H2O using microwave radiometry
Sammanfattning : Long series of continuous measurements of middle and upper atmospheric constituents are needed to be able to understand the anthropogenic influence on the atmosphere. Phenomena like ozone depletion and the enhanced greenhouse effect are examples where the role of human activities has to be well investigated in order to make the right decisions of necessary changes in our way of life.

2. Microwave remote sensing of ozone and other species in the middle atmosphere
Sammanfattning : .... LÄS MER
3. Development of sensitive EPR dosimetry methods
Sammanfattning : Electron paramagnetic resonance (EPR) dosimetry using the well established dosimeter material alanine is a generally accepted dosimetric method for measurements of high absorbed doses. Alanine EPR dosimetry is however not sensitive enough for high precision measurements of low (< 5 Gy) absorbed doses using reasonably measurement times and small dosimeters. LÄS MER
4. Surface Characterization using Radiometric and Fourier Optical Methods
Sammanfattning : This thesis treats static and dynamic surface characterization using radiometric and Fourier optical methods. A Fourier optical method has been developed for real time image processing in paper production and printing applications. LÄS MER
5. Inversion of microwave limb sounding observations of the atmosphere by a neural network technique
