Extended Data Fig. 4: The main source and sink profiles of SO2 in our WASP-39b model.
From: Photochemically produced SO2 in the atmosphere of WASP-39b

The reaction rates of the main sources and sinks of SO2 in the VULCAN morning-terminator model for WASP-39b. The dashed lines of the same colour are the corresponding reverse reactions and the dotted black line indicates the distribution profile (arbitrarily scaled) of SO2.
