Abstract
Leaf Area Index (LAI) and Canopy Closure (CC) were measured from April to October of 2010 at up to 70 points in the watershed about every two weeks (twice a month). At each point, LAI and CC were measured in four directions and averaged. Soil moisture was measured at many of the same points on a regular basis. LAI was measured using a LAI-2200 instrument (LI-COR Biosciences). Canopy closure was measured with a spherical densiometer, Model C Forest Densiometers).

Leaf Area Index (LAI): LAI-2200, LI-COR Biosciences. Percent Canopy closure (PCC): Spherical Densiometer, Model C, Forest Densiometers. Column headings indicate date (all in year denoted in filename). E.g., 'LAI520' is Leaf Area Index that used measurements from 5/20. See data file for additional information on methods used. PhenoCam project is a collaboration of Harvard University Richardson Lab, University of New Hampshire Earth System Research Center, Boston University Department of Earth & Environment, and Washington University in Saint Louis Media and Machines Lab - AMOS Project.
