This year, the station PIs of ICOS Ecosystem stations gathered for the ICOS Ecosystem Monitoring Station Assembly (MSA) meeting in Madrid (25-27 March 2025).
Iris Feigenwinter (ICOS Station PI for the Davos station) went to Madrid to represent ICOS-CH and the Davos station. At the meeting, the MSA discussed CO2 fluxes, sampling and calibration, documentation (BADM), the FLUXNET 2025 initiative, and further ICOS-related topics, ending with a group exercise on ICOS keywords. There was also an excursion to las Majadas de Tiétar, an ICOS station in the unique Dehesa ecosystem, which is an amazing workplace for scientists. While the grass is grazed by cattle, the dominant tree species is holm oak (Quercus ilex). Its acorns can be eaten by pigs, resulting in the famous Ibérico ham.
