Research paper thumbnail of Impacts of land use change due to biofuel crops on carbon balance, bioenergy production, and agricultural yield, in the conterminous United States

Switching from food crops to biofuel crops is an option to meet the fast-growing need for biofuel feedstocks. This land use change consequently affects the ecosystem carbon balance.

Six key parameters that govern the rates of carbon and nitrogen dynamics in TEM are selected for calibration. Spatially explicit data for carbon and nitrogen pools and fluxes are used to calibrate the six key parameters to more adequately account for the spatial heterogeneity of ecosystems in estimating regional carbon dynamics.

As the radiosity method is based on a global solving technique, the RGM can only deal with limited numbers of polygons, and has only been used for small-scale flat terrain scenes.

The analysis estimates that terrestrial areas of the Arctic Basin lost 62.9 Tg C yr− 1 and that the Arctic Ocean gained 94.1 Tg C yr− 1. Arctic lands and oceans were a net CO 2 sink of 108.9 Tg C yr− 1, which is within the range of uncertainty in estimates from atmospheric inversions.

Research paper thumbnail of Modeling temperature acclimation effects on carbon dynamics of forest ecosystems in the conterminous United States

To date, the acclimation of plant photosynthesis to rising temperature has not been adequately considered in earth system models. Here we present a study on regional ecosystem carbon dynamics under future climate scenarios incorporating temperature acclimation effects into a large-scale ecosystem model, the terrestrial ecosystem model (TEM).

We used a biogeochemistry model, the Terrestrial Ecosystem Model (TEM), to examine the methane (CH 4) exchanges between terrestrial ecosystems and the atmosphere in Northern Eurasia from 1971 to 2100. Multiple model simulations using various wetland extent datasets and climate change scenarios were conducted to assess the uncertainty of CH 4 fluxes, including emissions and consumption.

Using these remote sensing data and eddy flux measurements and biogeochemical models, such as the Terrestrial Ecosystem Model (TEM), should provide a more adequate quantification of carbon dynamics of terrestrial ecosystems.

We estimate that the global soil N2O source strength from natural ecosystems is 3.37 Tg (1 Tg= 1012 g) N per year with an uncertainty ranging from 1.96 to 4.56 Tg N per year in 2000. While our global estimate is lower than other existing estimates, the spatial patterns of our simulated N2O emissions agree with other existing studies.
