Papers are invited for Session B25: "Methane: Recent Findings (and
Surprises) at the Local and Regional Scale and Approaches to Reduce
Uncertainty in the Global Budget" being convened at the AGU Fall Meeting
on 10-14 December 2007 in San Francisco, California.
Session description:
Methane is a critical contributing component to the atmosphere's
radiation balance and oxidation chemistry. Despite its significance,
many surprises remain to challenge our understanding. Recent
observations have raised questions about methane's global source
distribution (satellite observations of the size and timing of tropical
sources), magnitude and mechanisms of evasion (lakes and reservoirs),
and even the potential of novel sources (upland plants) to affect the
global budget. This session will gather experts taking a broad range of
approaches to: 1) communicate current information on the mechanisms of
methane emission from reservoirs, lakes, and vegetation; 2) communicate
the current state of the assessment of the accuracy and the uncertainty
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 cooperative mechanistic
approaches in reducing uncertainties and expanding our quantitative
understanding of methane emissions from the Earth's surface.
