| Zusammenfassung |
| As part of the MACCII-project (EU-FP7) ECMWF's integrated forecast system (IFS) is being extended by modules for chemistry, deposition and emission of reactive gases. This integration of the chemistry complements the integration of aerosol processes in IFS.
C-IFS (Composition-IFS) provides global forecasts and analysis of atmospheric composition. Atmospheric chemistry in C-IFS can be represented by several chemical scheme, including RACMOBUS scheme as already implemented in the MOCAGE Chemistry-Transport-Model.
We will show the comparison of online versus offline use of the RACMOBUS scheme in an otherwise identical model setup (emissions, meteorology) over a one year run.
We will focus on global mass budget on troposphere and stratosphere, and validate fields of O3, NOx, CO and HCHO. |
