Understanding tree transpiration variability is vital for assessing ecosystem water-use efficiency and forest health amid climate change, yet most landscape-level measurements do not differentiate individual trees. Using canopy temperature data… More
Wetlands are an important component of the New England landscape, the Harvard Forest has its share; about 25% of the landscape is classified wetland or very poorly drained. Read how the The AmeriFlux instrument loaner program was used for a new pilot study at Harvard Forest.
Climate change is affecting the phenology of terrestrial ecosystems. In deciduous forests, phenology in leaf area index (LAI) is the primary driver of seasonal variation in the fraction of absorbed… More
Linking biometric measurements of stand-level biomass growth to tower-based measurements of carbon uptake—gross primary productivity and net ecosystem productivity—has been the focus of numerous ecosystem-level studies aimed to better understand… More

What happens when the dominant tree species in a forest is killed off by an insect pest? Eastern hemlock (Tsuga canadensis) is considered a foundation species with a range spanning… More
Last year, the AmeriFlux database hit a big milestone: 3000 years of site data in our half-hourly Flux/Met data (BASE) product! This achievement is a great testament to the collaboration… More
Climate extremes such as heat waves and droughts are projected to occur more Frequently with increasing temperature and an intensified hydrological cycle. It is Important to understand and quantify how… More
Large datasets of greenhouse gas and energy surface-atmosphere fluxes measured with the eddy-covariance technique (e.g., FLUXNET2015, AmeriFlux BASE) are widely used to benchmark models and remote-sensing products. This study addresses… More
How, where, and why carbon (C) moves into and out of an ecosystem through time are long‐standing questions in biogeochemistry. Here, we bring together hundreds of thousands of C‐cycle observations… More
