Fig. 8. Estimated cumulative CO₂–C loss predicted by temperature/CO₂ flux relationships as function of time-of-day when measurements are taken. In each panel, the different curves are results obtained by different temperature correction algorithms. All closed symbols are corrections based on the 0.05-m soil temperature: closed circles, variable Q₁₀ relationship; closed diamonds, Q₁₀ = 2.00; closed squares, Q₁₀ = 1.50; closed triangles, Q₁₀ = 1.25. All open symbols are corrections based on air temperature: open triangles, Q₁₀ = 1.25, open squares, Q₁₀ = 1.50; open diamonds, Q₁₀ = 2.00.
