報告人簡介

   Dr. Jennifer (Jenny) Watts is an associate scientist and research lead at the Woodwell Climate Research Center (woodwellclimate.org) in Falmouth, Massachusetts. She is also an affiliate professor of remote sensing in the Department of Land Resources and Environmental Sciences at Montana State University in Bozeman, Montana. Dr. Watts' work focuses on using a combination of field observations, satellite remote sensing, and models to improve understanding of the terrestrial high latitude carbon (i.e., carbon storage, CO2 and CH4 flux) and water cycle. Dr. Watts also applies a similar approach to quantify the carbon cycle and carbon storage in semi-arid rangelands. Watts is co-lead of the NASA Arctic Boreal Vulnerability Experiment (ABoVE; //above.nasa.gov/) carbon group and is principal investigator of arctic and boreal projects for the US National Science Foundation.


報告簡介

        The Arctic-boreal region is warming at rates higher than elsewhere on Earth. This warming is leading to substantial thaw of frozen ground and changes in surface hydrology, in addition to increasing the vulnerability of stored carbon to conversion as potent greenhouse gases, including methane (CH4). This presentation provides an overview of the state of knowledge for high latitude methane budgets and explores sources of uncertainty arising from model approaches, and limitations within existing remote sensing products used to inform model simulations across the large region. Additionally, I also highlight opportunities for future research.
