Webecosystem productivity (NEP) over North America in 2004 was 1.73 0.37PgCyr1, and this NEP value is reduced by 0.616PgCyr1 for the carbon loss due to harvested prod-uct emission, river/stream evasion, and fire emission in order to estimate the total land sink. These top-down and bottom-up estimates at the continental scale broadly agree, giving us WebThis is done through a process called atmospheric inversion, which uses transport models of the atmosphere to link the observed concentrations of CO2, CH4 and N2O to the net fluxes at the Earth's surface. By correctly modelling the winds, vertical diffusion, and convection in the global atmosphere, the observed concentrations of the greenhouse ...
