2021 SpecNet Community Meeting

SpecNet is a voluntary collaboration of investigators around the world who are combining proximal remote sensing approaches with flux and other field measurements. Typically, this involves field optical sampling that matches the spatial and temporal scale of flux measurements - providing a proxy measure of vegetation structural, physiological, and phenological properties, all of which provide indicators of ecosystem composition, function, and biosphere–atmosphere gas exchange. Ground-based optical sampling is particularly important in validating these relationships and adds to the value of field sampling networks and satellite/aircraft remote sensing studies.
