| Zusammenfassung |
| We describe version 2.0 of the chemistry-climate model (CCM) SOCOL. The new
version includes fundamental changes of the transport scheme such as
transporting all chemical species of the model individually and applying a
family-based correction scheme for mass conservation for species of the
nitrogen, chlorine and bromine groups, a revised transport scheme for ozone,
furthermore more detailed halogen reaction and deposition schemes, and a new
cirrus parameterisation in the tropical tropopause region. By means of these
changes the model manages to overcome or considerably reduce deficiencies
recently identified in SOCOL version 1.1 within the CCM Validation activity
of SPARC (CCMVal). In particular, as a consequence of these changes,
regional mass loss or accumulation artificially caused by the
semi-Lagrangian transport scheme can be significantly reduced, leading to
much more realistic distributions of the modelled chemical species, most
notably of the halogens and ozone. |
