This winter term we have the pleasure to host Prof. Chuixiang (Tree) Yi as a visting Fullbright Professor. During his stay he plans to work with group members on links between atmospheric boundary layer dynamics and ecosystem exchange processes. The picture below shows Tree and Kathi visiting the FAIR site flux tower.
This week Magnus Bremer (Institute of Geography, University of Innsbruck) used the great weather conditions to do a drone flight (video) with a laser scanner for the 3D reconstruction of canopy structure and a thermal imager. Here the aim is to fuse these data in order to improve remote sensing based modeling of evapotranspiration (picture and movie © Magnus Bremer).
After intensive preparations this week, today we started, within the frame of a joint FWF-DFG project with Mirco Migliavacca, a mesocosm experiment in which we aim to study the interactive effects of drought and canopy structure on the top-of-canopy sun-induced fluorescence. To this end, Javier Pacheco-Labrador joined with a FLOX-TOGO instrument for SIF measurements across the replicated plots on a planophile (clover) and erectophile (grass) canopy. These episodic measurements will be accompanied by a suite of additional measurements including active chlorophyll fluorescence, environmental conditions, leaf area, leaf angle distribution, leaf ingredients, etc. FormerMSCA fellow in our group, Karolina Sakowska, also joined for the day to help out, exchange data and discuss ongoing works!
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.
