FLUXNET is a global network of micrometeorological tower sites that use eddy covariance methods to measure the exchanges of carbon dioxide, water vapor, and energy between terrestrial ecosystem and atmosphere. At present, over 400 tower sites are operating on a long-term and continuous basis. Researchers also collect data on site vegetation, soil, hydrologic, and meteorological characteristics at the tower sites.

FLUXNET data available at the ORNL DAAC include monthly and annual heat, waper vapor, and carbon dioxide flux, gap-filled flux products, ecological site data, and remote-sensing products.

FLUXNET provides information to FLUXNET investigators and the public. The goals of FLUXNET are to understand the mechanisms controlling the exchanges of carbon dioxide, water vapor, and energy across a spectrum of time and space scales.

FLUXNET also provides ground information for validating estimates of net primary productivity, evaporation, and energy absorption that are being generated by sensors on the NASA TERRA satellite.
