Clone this wiki to obtain every listed namelist, streams file, mechanism, and photolysis/emissions configuration:
git clone https://github.com/NCAR/CheMPAS-A.wiki.git
cd CheMPAS-A.wiki/examplesThe examples are declarative inputs. The pages give manual staging and launch steps, while the source and data remain independently obtainable.
The Docker workflow automates bounded variants of Supercell ABBA, Supercell LNOx, and Global Chapman + NOx. It does not package the complete example collection below.
| Case | What it exercises | Nominal run |
|---|---|---|
| Mountain-wave ABBA | Runtime species, scalar transport, MICM reversible toy chemistry | 5 hours |
| JW baroclinic-wave ABBA | Global transport, runtime species, restart-capable streams | 16 days |
| Supercell lightning NOx | TUV-x jNO2, fixed idealized solar coordinates, lightning source |
60 seconds |
| Global Chapman + NOx | Runtime chemistry tracers, spatial solar geometry, TUV-x upper extension | 24 hours |
| Global emissions scenarios | Prescribed upper O3, CAMS emissions, FINN emissions, attribution differences | 24 hours each |

ABBA is a coupling/transport mechanism. Chapman + NOx is a reduced photochemistry test. The expanded global mechanism adds a compact Ox-HOx-NOx-CO-CH4 system. None is a substitute for a fully evaluated chemical mechanism and spun-up, assimilated global composition state.
