The CAMS IFS cycle 49R1 is based on ECMWF's IFS Cycle 49r1. This is a major an upgrade with various a limited number of scientific contributions for the atmospheric composition aspects. Key elements are ...an update of the global emissions to the CAMS-GLOB-ANT 6.1 dataset and improvements to the modelling of aerosol. More information can be found below.

Model changes
- CAMS-GLOB-ANT 5.3 (based on EDGAR 5, used in 48r1) has been replaced by CAMS-GLOB_ANT 6.1 (based on EDGAR 6 and 7)
Model changes
- Improvements to the aerosol removal processes (wet deposition) and aerosol ageing in the atmosphere
- Modelling of the formation of (secondary) aerosol from precursor gases with more detail (EQSAM4Clim module has been activated)A
Impact of the new cycle
A comprehensive evaluation report of the 49r1 e-suite, documenting all the changes and their impact on the forecasts will be provided ahead of the actual implementation. Initial testing results show ..improved aerosol forecasts.
