Contrail cirrus in the sky

Aircraft engines emit soot particles. These act as condensation nuclei for small, supercooled raindrops that freeze immediately to form ice crystals that are visible in the sky as contrails.

Cessna Grand Caravan measure emissions

View from the window of the DLR research aircraft Cessna Grand Caravan during a flight to measure emissions from coal mines and power plants in the Upper Silesian region.

The Institute of Atmospheric Physics investigates the physics and chemistry of the global atmosphere from the Earth's surface up to the stratosphere. The knowledge of the dynamic, cloud-physical and chemical processes taking place there forms the basis for a variety of applications in the aerospace industry. The relevant mechanisms and changes in the atmosphere are quantified and systematically investigated using remote sensing, measurement aircraft and computational models - both on a regional and global scale.
