The SMEAR II measurement station at Hyytiälä is located in a Scots pine dominate forest stand in southern Finland (61°51’ N, 24 °17’ E, 181 m altitude). The site is located on a haplic podsol soil over silty glacial till parent material. The forest was regenerated in 1962 by seeding after clear-felling and prescribed burning and is managed to mimic a local production forest. At the time of measurement (2017), trees had reached a height of 18 to 20 m. The forest was last thinned in 2002. Measurements were conducted on top of a scaffold tower located in a hilltop position. A detailed description of the forest stand is available in ref. 48. Shoot flux measurements were conducted weekly between July 7 and August 15 2017 on two Scots pine trees next to a scaffold tower.
