ECMWF implemented a new upgrade 49R1 of the CAMS (Copernicus Atmosphere Monitoring Service) global real-time data assimilation and forecasting system on 12 November 2024 for the 12UTC cycle.
Key elements are:
- Change in the assimilated observations.
- Changes to the aerosol and reactive gases modeling.
- Prescribed emissions have been updated to more recent versions.
The CAMS Global atmospheric composition forecast data documentation and the CAMS: Global greenhouse gases forecasts data documentation have been updated accordingly.
Please note that the data will be published with about 2 hours delay than usual time for the 12UTC run on 12 November 2024 and and the 00UTC run on 13 November 2024.
