Thermodynamics, Aerosol, Clouds in the Arctic Atmosphere

Climate change is most pronounced in the Arctic. Long term observations and process studies of essential climate variables are needed in order to understand its causes and impacts.

Arctic observations – with a special focus on the Svalbard region - are analysed and combined with modelling to understand and quantify the contribution of various climate parameters to climate change.

Observations and Analyses

The main data source for the section “Atmospheric Physics” is the atmospheric observatory at the AWIPEV research base in Ny-Alesund, Svalbard.

Our main Science Topics, as defined within PACES Research Unit 1a deal with the quantification of different factors affecting Arctic climate change like changing synoptic patterns, increasing long wave radiation, boundary layer processes, or seasonal aerosol forcing.

For this, we employ

These works are integrated in various activities and national and international projects.

Observations and Modelling

Observational data is valorized in our section twofold.

Observations are utilized for model validations and parameterisation improvements on regional and local scales. 

Moreover we apply regional model outputs for the interpretation of long term changes as observed at our station on Svalbard in a regional and Arctic wide context.
