Toward an understanding of methane fluxes on response to environmental change.

Session ID#: 161438

Session Description:
We need to improve our mechanistic understanding of methane (CH4) fluxes across ecosystem types in response to changes in environmental conditions (e.g., climate, land use / land cover). Remote sensing, land surface models, and observations can provide valuable information about the impacts of the changing climate and anthropogenic drivers on CH4 fluxes. As such, this session solicits abstracts that use models, observations, or a combination thereof, to provide new insights on CH4 dynamics in terrestrial, wetland, and freshwater aquatic ecosystems. Ecosystem response studies, as well as studies that quantify CH4 flux uncertainty are encouraged. We also invite studies that address: (1) developing improvements to current experimental designs aimed at understanding CH4 soil-vegetation interactions; (2) methods for reconciling different spatial and temporal scales between observations and model processes; (3) studies investigating the spatial and temporal variability in the different CH4 pathways; and 4) studies examining the role of observational errors and model uncertainties on CH4 fluxes.
