A Carbon Flux Super Site: New Insights and Innovative Atmosphere-Terrestrial Carbon Exchange Measurements and Modeling (Final Report)
Approximately around January 2010, instrumentation was setup and became operational on a permanent AmeriFlux flux tower at the Savannah River Site (SRS, see Figure 1), Aiken, SC, which has been named AmeriFlux Aiken site. Monitoring of key ecosystems in that region has been in process since March, 2010. We have made long-term measurements in the SRS region since December 2008, with a set of instrumentation including eddy-covariance systems, two SODARs, two microbarograph arrays, a soil heat flux system, and automated soil CO 2 efflux systems. The launching of the AmeriFlux Aiken site follows previous intensive field campaigns in 2007, 2008, and 2009 involving lidar, tethered balloon, scintillometer measurements, and tracer releases. Given the zero-tolerance for risk and the rigor of the contracting a company to operate at the national laboratory, the AmeriFlux core data collection portion of our project’s initial timeline was delayed to ensure maximum safety for all working at the site, but all aspects of the planned research are now fully functional and the project has been successfully taking flight. A rich database, unseen at most flux sites is now available for modeling while the present project uses this data to identify sources of uncertainties in flux measurements and create methodologies to reduce flux-related errors. Long-term measurements are well underway at the new AmeriFlux Aiken site.
