Terrestrial lidar scans were captured using a BLK360 scanner (Leica Geosystems, Norcross, GA, USA) which has a range of 0.5 – 45 m and measurement rate up to 680,000 points s−1 at the high-resolution setting. A georeferenced, 3-D point cloud of the study site was generated from 12 scans, approximately 50 m apart in both horizontal directions. Scans were performed in orientations intended to maximize branch exposure to the scanner and to scan during optimal weather conditions to minimize occlusion of features due to noise or movement generated by wind. Scan co-registration was done in Leica Geosystem’s Cyclone Register 360 software using its Visual Simultaneous Localization and Mapping algorithm (Visual SLAM) and resulted in relatively low overall co-registration error ranging from 0.005-0.009 m. From this study site point cloud, manual straight-line measurements from the ground to the sensors were made using Leica’s Cyclone Register 360 software. 

The attached datasets are from the publication: Drought decreases water storage capacity of two arboreal epiphytes with differing ecohydrological traits. Canopy epiphytes, plants that grow on trees, can have a significant influence on canopy water storage, interception, and precipitation fluxes. However, the drought response of the plants at a foliar level may influence their ability to store and capture rainfall. We experimentally tested the effects of leaf desiccation on water storage (Smax) and relevant leaf properties of two canopy epiphytes common in coastal maritime forests in Georgia, U.S.A.
