    Time: 12:00 to 4:00 PM EDT

    About Specnet

    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.

    Meeting Goals

    The goals of this year’s SpecNet Community Meeting are to provide opportunities for investigators to describe their work, present results, discuss new approaches, encourage new investigators, develop network-wide studies, and to advise SpecNet on how to advance these activities.
