Mud volcanoes and microseepage: the forgotten geophysical components of atmospheric methane budget
methane lithosphere degassing mudvolcanoes greenhouse gas geodynamics
2015/9/10
Mud volcanoes and microseepage are two important natural sources of atmospheric methane, controlled by neotectonics
and seismicity. Petroleum and gas reservoirs are the deep sources, and faults and f...
The consumption of atmospheric methane by soil in a simulated future climate
consumption atmospheric methane soil simulated future climate
2010/1/21
A recently developed model for the consumption of atmospheric methane by soil (Curry, 2007) is used to investigate the global magnitude and distribution of methane uptake in a simulated future climate...
Hemispheric average Cl atom concentration from 13C/12C ratios in atmospheric methane
Hemispheric average Cl atom concentration 13C/12C ratios atmospheric methane

Methane is a significant atmospheric trace gas in the context of greenhouse warming and climate change. The dominant sink of atmospheric methane is the hydroxyl radical (OH). Recently, a mechanism for...
Atmospheric methane and carbon dioxide from SCIAMACHY satellite data: initial comparison with chemistry and transport models
Atmospheric methane carbon dioxide SCIAMACHY satellite data chemistry and transport models

Little is known about how the methane source inventory and sinks have evolved over recent centuries. New and detailed records of methane mixing ratio and isotopic composition (12CH4, 13CH4 and 14CH4) ...
Four-dimensional variational data assimilation for inverse modelling of atmospheric methane emissions: method and comparison with synthesis inversion
Four-dimensional variational data atmospheric methane synthesis inversion
2008/11/25
A four-dimensional variational (4D-Var) data assimilation system for inverse modelling of atmospheric methane emissions is presented. The system is based on the TM5 atmospheric transport model. It can...
