Global high-resolution simulations of CO2 and CH4 using a NIES transport model to produce a priori concentrations for use in satellite data retrievals
Global high-resolution simulations CO2 and CH4 NIES transport model produce a priori concentrations satellite data retrievals
2014/12/17
The Greenhouse gases Observing SATellite (GOSAT) measures column-averaged dry air mole fractions of carbon dioxide and methane (XCO2 and XCH4, respectively). Since the launch of GOSAT, model-simulated...
Chemolithoautotrophic production mediating the cycling of the greenhouse gases N2O and CH4 in an upwelling ecosystem
Chemolithoautotrophic production the greenhouse gases N2O and CH4 an upwelling ecosystem
2010/1/21
The high availability of electron donors occurring in coastal upwelling ecosystems with marked oxyclines favours chemoautotrophy, in turn leading to high N2O and CH4 cycling associated with aerobic NH...

Influence of CH4 and H2S availability on symbiont distribution,carbon assimilation and transfer in the dual symbiotic vent mussel Bathymodiolus azoricus
CH4 H2S availability symbiont distribution carbon assimilation Bathymodiolus azoricus
2010/1/18
High densities of mussels of the genus Bathymodiolus are present at hydrothermal vents of the Mid-Atlantic Ridge. It was previously proposed that the chemistry at vent sites would affect their sulphid...
松辽盆地深层火山岩储层中的CH4包裹体:产状特征及其地质意义
松辽盆地 深层油气藏 火山岩储层 ＣＨ４包裹体
2014/3/27
营城组火山岩是松辽盆地深层油气藏的主要储层之一，本次研究我们在该组火山岩中首次发现了较多的纯ＣＨ４包裹体，这类包裹体主要以原生及次生形式产于流纹岩石英斑晶及玄武岩气孔充填矿物石英之中。综合分析认为，伴随营城组火山岩喷发活动，产生了较多的无机成因的ＣＨ４等气体，它们连同可能存在的其它有机成因的烃类气体一起，沿流纹岩中的微裂隙及玄武岩中的气孔等构造运移、聚集，从而形成深层火山岩储层中的富ＣＨ４天然气藏...
Modelling CH4 emissions from arctic wetlands:effects of hydrological parameterization
CH4 emissions arctic wetlands effects hydrological parameterization
2010/1/15
This study compares the CH4 fluxes from two arctic wetland sites of different annual temperatures during 2004 to 2006. The PEATLAND-VU model was used to simulate the emissions. The CH4 module of PEATL...
平流层CH4的时空变化特征及其与O3的关系
CH4 O33 平流层 时空变化特征
2012/11/9
利用1991年10月到2005年11月的HALO3E卫星观测资料,对全球70°S～70°N范围内平流层100hPa到1 hPa的大气CH4混合比进行了时空特征分析.结果表明:①CH4混合比在平流层是随高度上升而逐渐减小的.平流层中上层CH4变化存在年循环,而平流层中下层CH4变化存在半年振荡(SAO3),且南半球平流层CH4的季节变化振幅要大于北半球,特别是平流层中上层.平流层各个高度上的CH4基...
