This and the last week, Kadmiel Maseyk (Open University, UK) was visiting the group in order to prepare the 2nd COS workshop and discuss science and potential joint projects revolving around COS, SIF and grassland response to climate change. His stay was generously funded through a BrittInn fellowship. The picture shows Kadmiel (leftmost) and part of the group (from left to right: Katharina, Kathi, Karolina and Georg) preparing for the nightly downhill sledge after hiking up to Rumeralm.
