Corrigendum to “Empirical validation of photon recollision probability in single crowns of tree seedlings” [ISPRS J. Photogramm. Remote Sens. 169 (2020) 57–72] (ISPRS Journal of Photogrammetry and Remote Sensing (2020) 169 (57–72), (S0924271620302380), (10.1016/j.isprsjprs.2020.08.027))

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 G_T should be subtracted from the quotient of DN_leaf,T/DN_{WR_leaf,T} (not from DN_leaf,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.
