Freshwaters are important emitters of carbon dioxide (CO2) and methane (CH4), two potent greenhouse gases (GHGs).
Global high-resolution simulations of CO2 and CH4 using a NIES transport model to produce a priori concentrations for use in satellite data retrievals

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...
对长岭凹陷深层天然气藏储层——营城组火山岩中发育的流体包裹体进行了详细研究,结果表明在火山岩发育的石英、方解石细网脉中均存在较多的碳质流体包裹体,单个包裹体激光拉曼光谱分析结果表明其主要为CO2及CH4两种类型的碳质包裹体.其中方解石细网脉体中发育有原生及次生CH4包裹体,而含CO2包裹体多以原生包裹体产于石英细网脉中.很多含CO2包裹体的石英细脉中发现了含CH4包裹体的方解石脉体的角砾,这就表明...

对河北开滦矿区不同变质程度的煤进行了纯CO2和纯CH4气体等温吸附实验，并用Langmuir模型、三参数BET模型和吸附势理论模型（DR，DA）对煤的吸附实验数据进行了拟合，检验了各模型的拟合程度。结果表明：中煤阶烟煤的马家沟矿9号煤（Ro, ran = 1.21%）对CH4和CO2吸附能力比低煤阶烟煤的林南仓矿11号煤（Ro, ran = 0.58...
