Atmospheric Remote Sensing and Climate System Research Group

Satellite-based Earth observation is a crucial resource for monitoring and studying climate and environmental change. Occultation technology using signals from global navigation satellites (GPS, Galileo) or Low Earth Orbit (LEO) satellites is a particularly suitable method for a global view of climate change and the Earth's atmosphere. Processing this satellite data, creating climate data sets, using them for climate research and developing new methods are the focus of the group, one of the leading international research groups in the field of radio occultation for atmospheric and climate research.

In the specific Alpine region, the WegenerNet is a pioneering experiment of the group: a new type of climate station network in the regions of Feldbach and Johnsbachtal (Styria/Austria) for observing weather and climate with spatial resolution on a 1-km scale.

Satellite data and ground data are used together with climate model simulations to investigate climate variability, climate trends, weather and climate extremes and their causes. The focus is on global climate change and building bridges to regional and local climate and environmental change in the Alpine region.

ARSCliSys cooperates closely with the Regional Climate working group in the joint research focus Hydrological Extremes in Climate Change. The group also works closely with the Department of Astrophysics & Geophysics at the Institute of Physics (partner institute of the Wegener Center at the Faculty of Natural Sciences) and is part of the Atmospheric and Climate Physics working group there. In addition, ARSCliSys collaborates with many renowned partners on site, nationally and internationally and actively contributes to setting the international research agenda in its field of research.
