Standard Tropospheric Chemistry - StdTrop

46 species, 26 advected tracers, 129 reactions

This is a basic tropospheric chemistry scheme with 8 emitted species, 102 gas-phase reactions, 27 photolysis reactions and interactive deposition schemes. The scheme simulates the Ox, HOx and NOx chemical cycles and the oxidation of CO, ethane and propane. Sulphur chemistry can be added (AerChem) to allow the use of the MODE aerosol scheme. This scheme is currently implemented in HadGEM2-ES, and is available in all model versions.
