Thank you for joining our virtual meeting!

Date: June 25

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.
