Lifetimes for different processes. Solid lines: photolytic lifetime Dotted lines: chemical (gas-gas) lifetime. Dashed lines: molecular diffusion timescale. (). The characteristic time for turbulent transport (H2/K) is also shown. This figure makes use of the H08 chemical scheme, where OH photolysis is not included, and H2CO is only lost via photodissociation.
