Fig. 6. Flux (f₀) estimation accuracy of the non-steady-state diffusive flux estimator as a function of headspace concentration (C_t) measurement precision and scaled deployment time (t/). Data are for fixed effective chamber heights h = 10 and 20 cm, and 30-min deployment periods on soil with air-filled porosity = 0.3. Data plotted represent the mean ±95% CI derived from 1000 simulated flux estimates. The dashed line represents flux estimation accuracy when C_t was measured without error.
