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!
