Harvard Forest Environmental Measurement Site

At Harvard Forest, we conduct long-term eddy-covariance measurements of atmosphere-biosphere exchange. Our system of continuous monitoring provides quantitative information, defining the sources and sinks for important atmospheric gases. By constructing long, continuous time series we can understand sources of variance and determine the factors that regulate concentrations and deposition fluxes of greenhouse gases and pollutants.

At the site, measurements of Net Ecosystem Exchange (NEE) for carbon, ozone, NOy, H2O, and energy have been made continuously for 10 years, along with comprehensive climatic, environmental, chemical, and ecological observations.  Site details, instrument information, and descriptions of specific research can be found below.
