Chopping-03 Project Profile
  (updated 09-Mar-2016)
Project Title:Changes in Shrub Abundance in Arctic Tundra from the Satellite High Resolution Record for the Arctic-Boreal Vulnerability Experiment and Impacts on Albedo
Project Lead: Mark Chopping, Montclair State University
Project Funding: 2015 - 2018
NASA (agency representative: Eric Kasischke)
Project Type:NASA -- joined ABoVE in 2015
Solicitation:NASA: Terrestrial Ecology (2014)
Abstract: This project uses semi-automated interpretation of high resolution imagery to assess th direction and magnitude of changes in shrub cover and aboveground biomass in Alaskan and Canadian Arctic tundra over a 10- to 15-year period to provide data that can be used to validate lower spatial resolution ABoVE remote sensing data products, initiate, drive ...
