LAHV {leafR} | R Documentation |
Calculates the leaf area height volume (LAHV) metric as described in Almeida et al. (2019).
LAHV(lad_profile, LAI.weighting = FALSE, height.weighting = FALSE)
lad_profile |
output of the lad.profile function |
LAI.weighting |
boolean, define if LAVH should be weighted by total LAI. default FALSE |
height.weighting |
boolean, define if LAVH should be weighted by the max height. default FALSE |
A numeric
containing the Leaf Area Heght Volume calculated from the Leaf Area Density profile.
