The atmosphere safeguards the Earth from harmful radiation, regulates temperature differences and circulates thermal energy, water and pollutants: almost all life depends on this delicate protective layer. We monitor atmospheric phenomena and processes from their origin up to their impacts on climate change in order to better understand and predict trends. The focus: research on air quality, on feedback effects in the climate system and on future weather and extreme events.
The main goal of Topic 1 is to gain a better understanding of the role of the atmosphere in the climate system. To this end, the five Helmholtz Centres AWI, FZJ, GFZ, HZG, KIT study atmospheric processes by means of sophisticated measurements, laboratory investigations and numerical modelling. A key area of GFZ research in Topic 1 is the development and application of innovative approaches including satellite-based remote sensing methods based on Global Navigation Satellite Systems (GNSS). These shall be complemented with observations using the so-called VLBI - Very Long Baseline Interferometry. The GFZ is pioneering new atmospheric GNSS applications for climate, weather and ionospheric research. The reflected signals are primarily used to develop new methods for monitoring the Earth's surface. In this way it is possible to derive wind speeds or precipitation amounts over the oceans. Furthermore, soil moisture, vegetation and snow cover can also be monitored. A further research focus is the quantification of the vertical coupling between atmospheric layers using waves and tides, e.g. from the troposphere to the thermosphere and ionosphere. These activities are supported by geomagnetic and GNSS observations from the ground, from space and by numerical modelling. GFZ research in Topic 1 also concentrates on the Earth's magnetosphere and radiation belt. A noteworthy example is the impact of charged particles from the magnetosphere on the different atmospheric layers.
