Continuous tower-based measurements of the ecosystem-atmosphere exchange of CO2 and CH4 are presented, recorded over the period 2012–2018 and reported at a 30-minute time step at a sub-boreal forest in the northeastern United States. Additionally, we describe a five-year (2012–2016) dataset of chamber-based measurements of soil fluxes of CO2, CH4, and N2O (2013–2016 only), conducted each year from May to November. These data can be used for process studies, for biogeochemical and land surface model validation and benchmarking, and for regional-to-global upscaling and budgeting analyses.
