Welcome Guest   ( Sign In )

Overview

The National Center for Airborne Laser Mapping (NCALM) conducted a leaf-on survey of the Calhoun Critical Zone Observatory (CCZO) area on July 30, 2014 (hyperspectral imaging) and August 5-6, 2014 (LiDAR). The LiDAR survey was funded by NSF award EAR-1339015; the Calhoun CZO is funded by NSF award EAR-1331846 (P.I. Daniel deB. Richter).

Hyperspectral imaging data were also collected over the study area and are available via the following links:
