Matrix groups are networking platforms to foster cross-departmental collaboration, with the aim to prepare new projects in areas of strategic importance for the whole institute. These are our matrix groups:

Atmospheric methane cycle The long-lived greenhouse gas methane (CH4) plays an important role for our climate. A crucial point with respect to CH4 are the not fully understood changes in the growth rate during the recent decades. The Matrixgroup “Methane” facilitates networking between the corresponding research activities of the institute. Read more

Water vapour in the UTLS This matrix group is a cross-departmental think tank for discussing the role of water vapour in the upper troposphere and lower stratosphere (UTLS) for weather and climate. We seek synergies between airborne in situ and remote sensing measurements, as well as analyses using numerical weather and climate models. Read more

Effects of aerosols on climate The aim of the matrix group is to bundle the various methodical capacities of the institute to advance our understanding of the role of aerosols in the climate system. We perform combined analyses of data from aircraft-based in-situ measurements, different remote sensing techniques as well as global, regional, and process modelling. Read more

Natural clouds Clouds play a major role in the climate system and are responsible for a large part of the uncertainty in climate projections. Estimates of the impact of anthropogenic cloud changes require improvements in the understanding of cloud processes. The matrix group looks for synergies and for new possibilities of cross departmental cooperation. Read more

Middle atmosphere We develop powerful lidar instruments to explore the atmosphere to altitudes of more than hundred kilometers. Using data acquired during field campaigns and idealized modelling, we study the vertical coupling of the neutral atmosphere and the corresponding redistribution of energy and momentum by atmospheric waves throughout their life cycle.

Short-lived trace substances This matrix group seeks synergies between the various methodical capacities of the institute to deepen our understanding of short-lived trace substances. Those include trace gases like ozone and nitrogen oxides, which directly or indirectly affect the Earth's radiative balance, and also the oxidation capacity of the atmosphere. Read more
