Characteristics of free air carbon dioxide enrichment of a northern temperate mature forest.

ABSTRACT: In 2017, the Birmingham Institute of Forest Research (BIFoR) began to conduct Free Air Carbon Dioxide Enrichment (FACE) within a mature broadleaf deciduous forest situated in the United Kingdom. BIFoR FACE employs large-scale infrastructure, in the form of lattice towers, forming 'arrays' which encircle a forest plot of ~30 m diameter. BIFoR FACE consists of three treatment arrays to elevate local CO₂ concentrations (e[CO₂ ]) by +150 µmol/mol. In practice, acceptable operational enrichment (ambient [CO₂ ] + e[CO₂ ]) is ±20% of the set point 1-min average target. There are a further three arrays that replicate the infrastructure and deliver ambient air as paired controls for the treatment arrays. For the first growing season with e[CO₂
