The Walker Branch Watershed (WBW), Tennessee is part of the AmeriFlux
network of field research projects measuring the exchange of carbon
dioxide (CO2) between terrestrial ecosystems and the atmosphere.
The data at WBW are from 1995-1998 and consist of in situ
micrometeorological measurements of CO2, water, and energy exchange
rates using a 44-meter walkup tower.
The WBW AmeriFlux data and documentation is available from: http://cdiac.esd.ornl.gov/ftp/ameriflux/data/us-sites/walker-branch/
