Six years of ecosystem-atmosphere greenhouse gas fluxes measured in a sub-boreal forest.

ABSTRACT: Carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O) are the greenhouse gases largely responsible for anthropogenic climate change. Natural plant and microbial metabolic processes play a major role in the global atmospheric budget of each. We have been studying ecosystem-atmosphere trace gas exchange at a sub-boreal forest in the northeastern United States for over two decades. Historically our emphasis was on turbulent fluxes of CO₂ and water vapor. In 2012 we embarked on an expanded campaign to also measure CH₄ and N₂O. Here we present continuous tower-based measurements of the ecosystem-atmosphere exchange of CO₂ and CH₄, recorded over the period 2012-2018 and reported at a 30-minute time ste
