THE SPEULDERBOS FIDUCIAL REFERENCE SITE FOR CONTINUOUS MONITORING OF FOREST BIOPHYSICAL VARIABLES

摘要

This contribution describes the Speulderbos fiducial referencernsite for biophysical variables with a focus on foliagernvariables and Leaf Area Index (LAI). The site implementsrnUnmanned Aerial Vehicle (UAV)- and ground-based sensingrnsystems that aim at high temporal resolution observationsrnto capture fast canopy changes like spring leaf flush.rnIt aims at validating decametre resolution satellite observations.rnThe sensor systems and their respective samplingrndesign are described. Opportunities and restrictions of thernset up are discussed.
