A group of 19 participants from the ECOSENSE project (University of Freiburg, Germany) visited the Davos station on 31 July. Iris Feigenwinter (Davos station PI) gave them a tour around the station and explained the greenhouse gas and meteorological measurements at the forest floor and the 35 m tower. In the air-conditioned hut they could have a look at the data loggers and cabling, the fancy-valve switching system, and the online near real-time data visualization. Once more, we could use our excursion guide for the Davos station. Many questions were asked, and it was a pleasure to have such an interested and motivated group of scientists around!
