Natali-01 Project Profile
  (updated 26-Jun-2016)
Project Title:Winter respiration in the Arctic: Constraining current and future estimates of CO2 emissions during the non-growing season
Project Lead: Susan (Sue) Natali, Woods Hole Research Center
Project Funding: 2015 - 2019
NASA (agency representative: Eric Kasischke)
Project Type:NASA -- joined ABoVE in 2015
Solicitation:NASA: Terrestrial Ecology (2014)
Abstract: This proposal addresses the Tier 2 Science Question (3.6) of the Terrestrial Ecology solicitation (A.4): 'How are the magnitudes, fates, and land-atmosphere exchanges of carbon pools responding to environmental change, and what are the biogeochemical mechanisms driving these changes?' Over the past decades, surface air temperatures in the Arctic ha ... [more]
