Fig. 5: Schematic of the relevant reactions linking methane, HOx and NOx.
From: The role of future anthropogenic methane emissions in air quality and climate
Species that decrease in ZAME are labelled in blue, and those that increase in red. Solid arrows represent reactions, with labels referencing the relevant reaction in the Methods section. The dashed arrows show how OH and HO2 both contribute to the OH/HO2 ratio. This is a simplified schematic of a more complex system that includes more feedbacks, such as between HOx, NOx and ozone.
