System schematic. The Tree DEMON gas exchange study system design. a Purge air supply and conditioning; b chambers with sensors; c BVOC sampler unit containing four sampler strings with four ports each; d CO2 and water vapor gas exchange unit. Arrows indicate the direction of air flow. MFC mass flow controller, T/rH temperature and relative humidity sensor, T leaf leaf temperature sensor, PAR sensor photosynthetically active radiation sensor, SWC sensor soil water content sensor. A PID (proportional–integral–derivative) controlled valve was used to stabilize pressure to a constant level
