Aerosol forecasts

The operational CAMS global assimilation and forecasting system uses fully integrated chemistry in the ECMWF Integrated Forecasting System (IFS). The version of the IFS is named Composition-IFS (C-IFS). C-IFS makes it possible (i) to use the detailed meteorological simulation of the IFS for the simulation of the fate of constituents, (ii) to simulate atmospheric chemistry globally at high resolution because of the computational parallel efficiency of the IFS, (iii) to use the IFS data assimilation system to assimilate observation of atmospheric composition and (iv) to simulate feedback between atmospheric composition and weather. Different chemical schemes can be used with the current operational version being based on the CB05 scheme.

In the current configuration, chemistry originating from the TM5 CTM, has been fully integrated into the IFS forecasting model. This version applies 54 tracers and 120 reactions and focuses on tropospheric ozone-CO-NMVOC chemistry. Stratospheric ozone is modelled with a linearized scheme. A more extensive description can be found in this document.
