11. The Arctic Summer Atmosphere
Sammanfattning : The Arctic climate has experienced large changes over recent decades, the largest for any region on Earth. To understand the underlying reasons for this climate sensitivity, we need both models and observations. LÄS MER
12. Satellite measurements and climate modelling of water in the tropical upper troposphere
Sammanfattning : The International Panel on Climate Change (2007) has identified key areas of uncertainty with regards to future climate change, e.g., the upper troposphere. A portion of the uncertain- ties come from climate models and this makes model accuracy very important. LÄS MER
13. Precipitation phase determination in cold region conceptual models - analysis and method development
Sammanfattning : Precipitation phase uncertainty is a known source of error in conceptual models used for many hydrological, climatological, and environmental applications. These conceptual models often use the simple approach of calibrating an air temperature threshold (TRS) over a large area irrespective of physiographic characteristics such as distance to the ocean and topographic relief.

14. Lidar Studies of Tropospheric Aerosols and Clouds
Sammanfattning : An improved description of aerosol and cloud processes is a prerequisite for successful prediction of future climate change. The climate on Earth is controlled by the radiation budget, i.e. the relation between the radiation going into and out from the atmosphere. LÄS MER
