Atmospheric Composition monitoring (AC SAF)
Data on ozone and atmospheric chemistry
The AC SAF processes data on ozone, other trace gases, aerosols and ultraviolet data, obtained from satellite instrumentation.

The AC SAF develops, produces, archives, validates and disseminates ozone and atmospheric chemistry products, to support the services of the EUMETSAT Member States in weather forecasting, as well as monitoring of ozone depletion, air quality and surface UV radiation.
In addition, these products contribute to the implementation of the EUMETSAT strategy in environmental monitoring of the atmosphere. This is achieved at the European level by contributing to the Copernicus activities, and in the global scale by implementing the global observations of the key atmospheric parameters, as recommended by the Integrated Global Atmospheric Chemistry Observations Theme (IGACO) within the IGOS framework.
Application example for monitoring sulphur dioxide (SO2) levels
The GOME-2 instrument aboard EUMETSAT's polar-orbiting Metop-A satellite is also used to monitor sulphur dioxide (SO2) levels from volcanic eruptions across the globe. This visualisation shows the SO2 plume from the eruption of Mt. Kasatochi in the Aleutian Island chain as it moves across the globe between 7-21 August 2008.
