FLUXNET

Number of sites: 266 (October 2004)

FLUXNET - A global network of micrometeorological tower sites that use eddy covariance methods to measure the exchanges of carbon dioxide (CO₂), water vapor, and energy between terrestrial ecosystem and atmosphere. At present, over 200 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.

Detailed information about each site can be found at: http://www.fluxnet.ornl.gov/fluxnet/siteplan.cfm
