🎉 That's a wrap on #EGU26! A huge well done to all ICOS scientists who presented, convened sessions, and flew the flag for greenhouse gas science in Vienna this week.👏🌍 If you can't wait till #EGU27, join us in Lund in September for the ICOS Science Conference! More info: https://ow.ly/ByHf50YWy7C#EGU26

🌆🌱 At #EGU26, Lukas Emmenegger shared a useful “price vs. precision” rule for urban CO₂ monitoring: €100k → 0.1 ppm €10k → 1 ppm €1k → 10 ppm "Low-cost sensor" ≠ "low-cost network." The real investment lies in expertise, calibration, and data processing needed to make the data actionable.

🎉 Congratulations to Anne Klosterhalfen, postdoc at U. Göttingen and scientific coordinator of ICOS Hainich station, on receiving the #EGU26 Biogeosciences Outstanding ECS Award! Anne's work on ecosystem carbon fluxes is the kind of science that makes the ICOS community shine👏
