Methane Emission to the Atmosphere Bazhin N.M. Institute of Chemical Kinetics and Combustion Novosibirsk RUSSIA
Methane in Atmosphere – Concentration 1.8 ppm Content in Atmosphere 5000 Tg (1 Tg = 10 12 g = 1 mln of tons) Flux 500 Tg /year
Methane concentration dependence on time
Methane concentration and world population
Methane sources Emission from Swamps, Rice fields, Lakes and Oceans - 44%
Bubbles formation in rice field model
Upper border of bubbles position Dimensionless unit of depth
Artificial atmospheres: nitrogen - oxygen Kuzmin et all, Limnology and Oceanology
If W 1 (z) = W 10 then Transport in region I Border conditions N2N2
Transport in region II Main idea: - sink to the bubbles - molar part in the bubbles
Exponential approximation to W(z) W 1 (z) = W 10 exp(-νz)
CH 4 and N 2 concentrations on depth, W 1 (z) = W 10 exp(-νz)
Bubbles composition on depth
Methane concentration on depth
