Deep Remote Sensing Methods for Methane Detection in ...

The presence of methane gas (CH4) in the atmosphere is understood to be a chief contributor to global climate change. CH4 is a greenhouse gas with a Global Warm-ing Potential (GWP) 86 times that of carbon dioxide (CO2) [25]. CH4 accounts for 20%of global warming in-duced by greenhouse gases [19]. Although CH4 has many sources, oil and natural gas are of particular interest. Emis-sions from ...

Gas Sensors Methane -

Methane is a nontoxic, colorless, odorless gas. Methane is a gas produced by a group of colonic anaerobes. All methane produced by human beings is a metabolic product of intestinal bacteria, and about 50% of it is excreted. Methane is also found below ground and under the sea floor. It is emitted during production and transport of coal, natural gas, and oil, as well as from lifestock. Methane ...
