Part of the NATO ASI Series book series (volume 13)


At present the amount of methane removed from the atmosphere each year is about 500 Tg/yr or more than 90% of that released into the atmosphere each year. Most of the methane is removed by reacting with tropospheric OH radicals; lesser amounts are removed by soils and stratospheric oxidation by OH, O(1D), and minor reactions. This chapter is on the removal rate of CH4 and its variability in space and time.
