Is the spherical leaf inclination angle distribution a valid assumption for temperate and boreal broadleaf tree species (2013, background): “where 2 0 is the maximum standard deviation with expected mean t̄ and 2 t is variance of t (Wang et al., 2007).”
Estimating leaf inclination and G-function from leveled digital camera photography in broadleaf canopies (2011, background): “where r(2)0 is the maximum standard deviation with expected mean t and r(2)t is variance of t (Wang et al. 2007).”
Comparison of methods for measuring gap size distribution and canopy nonrandomness at Järvselja RAMI (RAdiation transfer Model Intercomparison) test sites (2011, methodology): “…special distributions have been developed to describe leaf inclination distribution function f( L) (for their overview see Weiss et al., 2004); Wang et al. (2007) evaluated the two-parameter Beta-distribution (Goel and Strebel, 1984) as the most appropriate for describing the probability…”
Photographic measurement of leaf angles in field crops (2014, methodology): “…leaves with a uniform distribution of azimuth angle, the LAD s fully described by the distribution of the leaf inclination angle. s demonstrated by Wang et al. (2007), natural leaf angle distriutions can be fitted reasonably well by the two-parameter beta istribution (Goel and Strebel, 1984).”
Modeling approaches to estimate effective leaf area index from aerial discrete-return LIDAR (2009, background): “, beta function) can be applied to augment this relationship for other leaf angle distributions such as ellipsoidal, horizontal, and vertical leaves (Jones, 1992; Wang et al., 2007).”
New estimates of leaf angle distribution from terrestrial LiDAR: Comparison with measured and modelled estimates from nine broadleaf tree species (2019, methodology): “The measured leaf inclination angles were fitted with the two-parameter Beta distribution (Goel and Strebel, 1984), which was shown to be the best suited for describing the probability density of θL (by Wang et al., 2007): = − − −f t B μ ν t t( ) 1 ( , ) (1 )μ v1 1 (3) where =t θ π2 /L .”
