TRAGNET United States Trace Gas Network Database

TRAGNET United States Trace Gas Network The United States Trace Gas Network (TRAGNET) is meant to accomplish two goals, including documenting contemporary fluxes of CO2, CH4 and N2O between regionally important ecosystems and the atmosphere, and determining the factors controlling these fluxes and improve our ability to predict future fluxes in response to ecosystem and climate change. The research for this project is funded by the National Science Foundation.

The atmospheric concentrations of greenhouse gases such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) are increasing substantially. These increases are expected to result in global warming and changes in precipitation patterns, and may directly affect terrestrial ecosystems. Our understanding of the contemporary fluxes of these gases between the land and atmosphere is incomplete.
