Figure 2: (Left) Comparison of Î´CR versus CO2 range using Keeling or Miller-Tans isotopic mixing relationships and Model I or Model II regression schemes using data collected by tunable diode laserâ€¦ (More)

[1] Separation of the net ecosystem exchange of CO2 (F) into its component fluxes of net photosynthesis (FA) and nonfoliar respiration (FR) is important in understanding the physical andâ€¦ (More)

Data assimilation, or the fusion of a mathematical model with ecological data, is rapidly expanding knowledge of ecological systems across multiple spatial and temporal scales. As the amount ofâ€¦ (More)

[1] Estimates of fossil fuel emissions on local to regional spatial scales and hourly to weekly temporal scales are increasingly useful in studies of the carbon cycle and mass and energy flow inâ€¦ (More)

Nitrous oxide (N2O) emissions within the US Corn Belt have been previously estimated to be 200â€“900% larger than predictions from emission inventories, implying that one or more source categories inâ€¦ (More)

We integrated soil models with an established ecosystem process model (SIPNET, simplified photosynthesis and evapotranspiration model) to investigate the influence of soil processes on modelledâ€¦ (More)

In this paper any non-homogeneous differential equation with constant coefficients is reduced to a matrix equation ~q = ~cP . For the discussion, ~q represents a matrix of constant coefficients toâ€¦ (More)
