1. Inversion of microwave limb sounding observations of the atmosphere by a neural network technique
Sammanfattning : .... LÄS MER
2. Satellite measurements of upper tropospheric water
Sammanfattning : Water vapour and clouds in the upper troposphere have strong influence on the Earth's climate system. The present uncertainties regarding the distribution and feedback mechanisms of water to a changing climate are today among the greatest limitations for accurate climate predictions. LÄS MER
3. Microwave Radiometric Observations of the Middle Atmosphere: Simulations and Inversions
Sammanfattning : Two well-known examples of global environmental problems are the ozone depletion and the enhanced greenhouse effect. The importance and the complexity of these questions generate a demand for improved atmospheric observations, and microwave radiometry is an approach which is increasingly important for measurements of the middle atmosphere (10-100 km).

4. Analysis of stratospheric ozone depletion in the Arctic using a data assimilation technique
Sammanfattning : Serious ozone depletion has been measured every Antarctic spring since the early 80’s. This ozone depletion is considered to be a result of photo chemical reactions and cat- alytic cycles resulting from anthropogenic halogen containing gases. LÄS MER
5. Decadal analysis of stratospheric ozone depletion using data assimilation and Odin/SMR measurements
Sammanfattning : Serious ozone depletion has been measured every Antarctic spring since the early 80’s. This ozone depletion is considered to be a result of photo-chemical reactions and catalytic cycles resulting from anthropogenic halogen containing gases. facilitated by the formation of Polar Stratospheric Clouds (PSCs).
