Huge interest in the world of data

With live measurements on a piece of meadow, the doctoral student Kathrin Fuchs (in the middle) showed impressively how the carbon dioxide exchange differs by day from the process at night. Sabina Keller (on the right) showed the evaporation of plants with a thermal imaging camera.

Virtual Reality flight to Davos

Under which conditions does an ecosystem bind more carbon than it releases and thus acts as a carbon sink? And when does this sink turn into a source and contribute to climate change? At the stand of the research group for Grassland Sciences, visitors were informed about the latest measurements from the past 20 years in the Seehornwald Davos. A virtual animation of the gas and energy exchange between ecosystems and the atmosphere was shown. It was thus possible to fly to the 40-meter-high observation tower and to observe the storage and release of CO₂ particles.

The atmosphere is full of invisible particles that are transported with the wind. They are in constant interaction with the biosphere. For example, CO₂ is an invisible gas and an important component of the atmosphere. For this roughly 3-minute tour the CO₂ was made visible and the visitors see, among other things, how the CO₂ particles in the air (blue-turquoise) are turbulently transported with the wind.
