The Transregional Collaborative Research Centre TR 172 (AC)³ provides a unique research environment to study the increase of Arctic near-surface temperature during the last decades, which is commonly referred to as Arctic Amplification, from complementary viewpoints, bridging various observations and modelling approaches.

University of Leipzig, as the coordinating University has applied together with the University of Bremen, University of Cologne and the Alfred-Wegener Institute for Polar and Marine Research (AWI), and the Leibniz Institute for Tropospheric Research (TROPOS) for support of this research project.

The overarching scientific objective of (AC)³ is to identify, investigate, and evaluate the key processes contributing to Arctic Amplification, improve our understanding of the major feedback mechanisms, and quantify their relative importance for Arctic Amplification.
