The role of clouds on the depletion of methane and water dominance in the transmission spectra of irradiated exoplanets [PDF]
, 2020 Observations suggest an abundance of water and paucity of methane in the majority of observed exoplanetary atmospheres. We isolate the effect of atmospheric processes to investigate possible causes. Previously, we studied the effect of effective temperature, surface gravity, metallicity, carbon-to-oxygen ratio, and stellar type assuming cloud-free ...

Three decades of global methane sources and sinks
, 2013 Methane is an important greenhouse gas, responsible for about 20% of the warming induced by long-lived greenhouse gases since pre-industrial times. By reacting with hydroxyl radicals, methane reduces the oxidizing capacity of the atmosphere and generates

Impact of Dynamic Elastic Modulus on Coal Permeability: Modeling and Analysis
Geofluids, 2022 Coalbed methane is a kind of high-quality clean energy. The underground gas drainage can achieve the efficient utilization of coalbed methane. Permeability is the key factor affecting gas drainage.

Absorption Coefficients of the Methane-Nitrogen Binary Ice System: Implications for Pluto [PDF]
, 2015 The methane-nitrogen phase diagram of Prokhvatilov and Yantsevich (1983) indicates that at temperatures relevant to the surfaces of icy dwarf planets like Pluto, two phases contribute to the methane absorptions: nitrogen saturated with methane $\bf{\bar{N_{2}}}$:CH$_{4}$ and methane saturated with nitrogen $\bf{\bar{CH_{4}}}$:N$_{2}$.

From the seep to the surface: the ascent and dissolution of methane bubbles in the ocean [PDF]
arXiv, 2018 Methane, as a strong greenhouse gas, has 21-25 times the warming potential per unit mass than carbon dioxide, and the methane from the oceans can contribute to ~4% of the annual atmosphere methane budget. Large methane bubble plumes have been observed in seep sites globally on shallow continental shelves, and emerging industry of methane hydrates ...

A Review of Methane Gas Detection Sensors: Recent Developments and Future Perspectives
Inventions, 2020 Methane, the primary component of natural gas, is a significant contributor to global warming and climate change. It is a harmful greenhouse gas with an impact 28 times greater than carbon dioxide over a 100-year period.

Oceanic and atmospheric methane cycling in the cGENIE Earth system model [PDF]
arXiv, 2020 The methane cycle is a key component of the Earth system that links planetary climate, biological metabolism, and the global biogeochemical cycles of carbon, oxygen, sulfur, and hydrogen. However, currently lacking is a numerical model capable of simulating a diversity of environments in the ocean where methane can be produced and destroyed, and with ...

Damage Effect and Injury Range of Shock Waves in Mine Methane Explosion
MethaneDuring the process of mining underground coal, the coal emits a large amount of methane into the mining space, which may lead to methane accumulation and exceed explosion safety limits When the methane encounters a fire source, a methane explosion may ...
