二氧化碳方差的预算方程可以用产生、耗散和通量散度项来表示。每一项都是在接近中性到中度不稳定的植被条件下测量的。通量散度项大约比产生项和耗散项小一个数量级，尽管它显示了0.006 < ζv< 1时的损失和1 < - ζv< 10时的增益。其中，ζ为含湿度影响的Monin-Obukhov稳定性参数。正如预算的闭包所期望的那样，无因次产生项和耗散项基本相同，并由相同的函数形式(1-16 ζv)−1/2表示。
The budget equation for carbon dioxide variance can be represented by production, dissipation and flux divergence terms. Each term is measured under near neutral to moderately unstable conditions over vegetated fields. The flux divergence term is about an order of magnitude smaller than production and dissipation terms, though it shows a loss for 0.006 < ζv< 1 and a gain for 1 < - ζv< 10. Here, ζvis the Monin-Obukhov stability parameter including humidity effect. As expected from a closure of the budget, the nondimensional production and dissipation terms are basically identical and represented by the same functional form: (1–16 ζv)−1/2.
