ECMWF is implementing the atmospheric service of the European COPERNICUS programme. The near-real-time production (analyses and forecasting) system is based on the Integrated Forecast System (IFS). In earlier versions, IFS was coupled to the chemistry transport model MOZART-3. Since 2014-09-18, C-IFS (composition IFS) with the on-line integrated TM5 chemistry is used.
The NRT stream produces analyses and forecasts of global stratospheric fields of O3.
Other reactive gases are available from the chemistry model. For comparison purpose we display also NOx (as NO+NO2 for CIFS-TM5 based model).
The CAMS o-suite is documented here.The pre-operational MACC o-suite was built up from a succession of experiments .
This succession of models and configurations is listed here by date of change in the resulting analyses:
- 2015-09-03, CIFS-CB05 g9rr based on C-IFS 41r1_CAMS: first implementation of the operational CAMS o-suite. The changes are described in the corresponding e-suite validation report and have no impact on stratospheric ozone.
- 2014-09-18, CIFS-CB05 g4e2 : this is a major switch, where CIFS-CB05 uses the photochemical module of TM5 which does not take stratospheric chemistry into account. The only product suitable for stratospheric composition is now ozone, thanks to data assimilation.
- 2014-02-24, IFS-MOZART fnyp : another change happens, e.g. IFS Cy40R2. The preparatory e-suite experiment was named fzpr. The final log_fnyp corresponds to that configuration.
- 2013-10-07, IFS-MOZART fnyp : several changes happen, e.g. IFS Cy38R2. The preparatory e-suite experiment was named fwu0
- 2013-01-07, IFS-MOZART fnyp : major change w.r.t. strato ozone: assimilated MLS data (NRT dataset) switches from v2.2 to v3.3. This fixes the vertical structure issues described by Lefever et al. (ACP, 2015)
- 2012-07-05, IFS-MOZART fnyp : started on originally with IFS Cy37R3.
- 2009-10-09, IFS-MOZART f93i : IFS Cy36R1 and assimilating (among other streams) the Aura-MLS v2.2 NRT ozone profiles. See log_f93i. The stratospheric ozone delivered by this experiment was validated in Lefever et al. (ACP, 2015).
A parallel stream built from preliminary experiments, know as the e-suite, is used for the next implementation of the o-suite.
