This configuration involves an extension to the UKCA Standard Tropospheric Chemistry (StdTrop) scheme to additionally include tropospheric aerosol-precursor chemistry.
In addition to the 26 advected tracers in StdTrop, 7 extra tracers are added for the aerosol chemistry. These consist of 4 sulphur species (DMS, SO2, MSA, H2SO4, ammonia and two organic species. The two organic species are a monoterpene tracer "MONOTER" and an oxidation product "SECORG" following the simple secondary organic aerosol production scheme developed for the GLOMAP-TOMCAT chemistry transport model (e.g. Spracklen et al, 2006).
The H2SO4 and SECORG tracers condense into the sulphate and organic carbon components in the GLOMAP-mode aerosol scheme.
Aqueous phase oxidation of SO2 by H2O2 and O3 is calculated based on an effective Henry's law approach and produces sulphate in the GLOMAP-mode accumulation and coarse soluble modes.
As for the StdTrop chemistry, this extended scheme (StdTrop+Aero)uses the Backward-Euler solver.
