Comments: Since 2013 in a collaborative project with the University of Potsdam we are measuring temperature, humidity and wind speed of the understory at two experimental plots, one in an open area, the other in a closed area (higher tree density). The spectral sensors facing the understory and the infrared sensor are set up at the same position of the open area.
