Townsend et al. (1) agree that we explain the observed relationship (2) between foliar nitrogen (%N) and near-infrared (NIR) canopy reflectance is largely due to structure - i.e.,
structural variation due to fraction of broadleaf canopy. Our conclusion that the observed correlation with %N is spurious (i.e., lacking a causal basis) is thus clearly justified: we
demonstrate that structure explains the great majority of observed correlation, where the structural influence is derived precisely via reconciling the observed correlation with
radiative transfer theory. [-]
