Dear Colleagues,
I would like to bring your attention to a CH4 session at Fall, 2006 AGU
meeting. You can see this will be a very exciting session as
contributions will range from field, lab, modeling, to remote sensing
studies related to CH4 cycling. Please consider to participate in the
event and feel free to spread the words to CH4 research community.
http://www.agu.org/meetings/fm06/ could let you submit your abstract.
Please notice the deadline of submission is 7 September. Look forward to
seeing you in this gathering.
B05: Methane: Toward a Multiscale Approach to Reducing Uncertainties in
Its Emissions
Methane is a component in the global carbon cycle. It plays important
roles in the global climate system and in determining background air
quality. Despite its significance, large uncertainties still exist in
methanes global budget, particularly for sources that vary over small
spatial and temporal scales, such as wetlands. There are ongoing bottom-up
approaches to reduce these uncertainties at the process level that meld
measurements of fluxes and ecosystem parameters with process-based models
and there are top-down approaches using space-based and in situ
measurements of the spatial distribution of methane combined with
atmospheric transport models. This session will gather experts taking both
approaches to: 1) communicate current information on the mechanisms of
methane emission from wetlands, rice paddies and other sectors (such as
vegetation, landfills, industrial emissions, and oceanic emissions); 2)
communicate the current state of in situ and satellite observations of
methane abundance and land cover, field experiments of methane emissions,
and modeling at various spatial scales; and 3) promote synthesis and
coordination between bottom-up and top-down approaches in reducing
uncertainties and expanding our quantitative understanding of methane
emissions from the earths surface.
