Past Projects

Carbon emissions from deforestation and forest degradation have been estimated to contribute 12–20% of total anthropogenic CO2 emissions, ranking as the second largest source of CO2 to the atmosphere, after fossil fuel burning. Global monitoring of forest biomass is therefore critical to understanding the global carbon balance, and to support international agreements on greenhouse gases and carbon markets.

Currently, remote sensing approaches used for verifying carbon fluxes from...

Nations of the world face challenges in developing sound policies and directions for addressing global change. The scientific community has the responsibility to provide the scientific basis for those policies. This includes developing the understanding of the influence of land, ocean and atmospheric processes in climate change. The goal of AmeriFlux is to develop a coordinated research network of long-term flux sites in the Americas for quantifying and understanding the role of the...

AmeriFlux is a network of 92 long-term research sites across North America measuring the exchange of water vapor, sensible heat, and carbon fluxes between the atmosphere and biosphere using the eddy covariance technique. As with every precision measurement endeavor, there are sources of systematic and random error resulting from variances in hardware, software, and the instrument installation. To reduce and quantify these uncertainties, the AmeriFlux quality assurance and quality control (QA...
