The authors regret that Eqs. (8) and (10) in the article are incorrect. In Eq. (8), 2π should be replaced by 1. In Eq. (10), the term GT should be subtracted from the quotient of DNleaf,T/DNWR_leaf,T (not from DNleaf,T in the numerator). The correct equations are: [Formula presented] [Formula presented] The errors were only in the article text and therefore did not influence the calculations or results of the study. The authors would like to apologise for any inconvenience caused.
