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).
Had a fantastic day out at the FAIR tower site mounting active and passive chlorophyll fluorescence measurement devices together with Michaela, Albin and Klemens, who filmed our activities for the upcoming MSc study Ecology & Biodiversity movie.
Here a few snapshots (© all pictures Klemens Weisleitner).
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, Albin, equipped with a special permit, went to Neustift to maintain field equipment and fix some issues.
As vegetation development is progressing, Lorenz and Rolando are using our unique EcoBot for investigating spatial differences in energy partitioning between locally grown crops across the precipitation gradient from Cordillera blanca to negra just outside Huaraz.
