Photographs of a surface enclosure experiment setup at Toolik Field Station, Alaska. (a) The first step of the installation consisted of positioning the Teflon base around the vegetation of interest along with temperature (T), relative humidity (RH), and photosynthetically active radiation (PAR) sensors. (b) The second step consisted of positioning the Tedlar® bag around the base. The bag was connected to a purge-air and a sampling line. An additional T/RH sensor was also positioned outside the bag.
