Fig. 3From: A low-cost automated growth chamber system for continuous measurements of gas exchange at canopy scale in dynamic conditionsPreliminary test results: measured CO2 fluxes after scrubbing inlet CO2 (negative values) or after injecting pure CO2 (positive values) versus modeled fluxes calculated using Eqs. 4 and 5 for photosynthesis and respiration, respectivelyBack to article page
