Abstract
Leaf Area Index (LAI) was measured in July-August 2014 in 36 15-m diameter plots located throughout the Calhoun CZO LiDAR flight area on approximately the same dates as the 2014 leaf-on LiDar flight. In each plot, LAI was measured in six directions (W, E, NE, SW, SE, NE) relative to the plot center. The individual readings are presented here. LAI was measured using a LAI-2000 (LI-COR Inc., Lincoln, NE).

| comments | LAI (Leaf Area Index) = foliage area per unit ground surface area (dimensionless); DIFN (Diffuse Non-interceptance) = fraction of sky visible (dimensionless); MTA = Mean Tip Angle; SMP = Number of A/B pairs included in the computation; se = standard error. Above-canopy readings were taken simultaneously with the below-canopy readings in a nearby open field. 90 degree view caps were used to block and possible extraneous readings from the operator. |
