Digital hemispheric photos of plot vegetation (DP1.10017.001)

This data product contains the quality-controlled, native sampling resolution field data and 180 degree hemispherical images that enable ground-based calculation of Leaf Area Index (LAI) and/or Plant Area Index (PAI). For forests, both upward-facing photos of canopy vegetation, and photos of understory vegetation are collected. For shorter-stature ecosystems, only downward-facing images of 'understory' vegetation are collected, where 'understory' is defined to include all vegetation. Photos are acquired with a full-frame DSLR camera equipped with a fisheye lens, and are provided in RAW image format. For additional details, see the user guide, protocols, and science design listed in the Documentation section in this data product's details webpage. Latency: The expected time from data and/or sample collection in the field to data publication is as follows, for each of the data tables (in days) in the downloaded data package.
