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!


Last week 31 scientists from 16 different countries met at the conference of the University of Innsbruck in Obergurgl in order to discuss the most recent research on carbonyl sulfide in a workshop organized by the Biometeorology group. As the pictures below show a lot of serious science happened, but we also had a lot of fun!
