Total percentage error (T) and percentage errors due to changes in air flux velocity (F) and in \(\Delta {\mathrm{C}\mathrm{O}}_{2}\) (\(\Delta\)) calculated from the partial derivation of Eq. 8. The parameter changes (x axis) are shown as normalized values (i.e. percentage change [0–100]) but the actual ranges of parameters are: F = [0.2: 0.6] mol s−1 and \(\Delta {\mathrm{C}\mathrm{O}}_{2}\)=[0: − 10] ppm. The boxplots show the aggregated values for all 12 chambers
