TRAGEX sought to improve the understanding of increased concentrations and fluxes between the soil and atmosphere of trace gasses such as CO2,, CH4, N2O impacts on climate and precipitation. TRAGEX studied the factors controlling the fluxes and improved the ability to predict future fluxes. The project greatly improved understanding of the fluxes of these gasses in areas such as Russia, China and temperate South America, which were largely unknown prior to TRAGEX.
