DESCRIPTION:Forecasting and data assimilation of atmospheric c
 omposition have become important activities at ECM
 WF as part of the MACC project. MACC makes daily g
 lobal forecasts and has produced a  re-analysis of
  atmospheric composition (2003-2010). Both data se
 ts are freely available and can be used for campai
 gn support\, provision of boundary conditions\, cl
 imatological studies or model evaluation.  We pres
 ent the modelling system for reactive gases and ho
 w it is used in the assimilation of satellite obse
 rvations. We will discuss the benefit of data assi
 milation using two examples: the forecast of the s
 evere pollution caused by fires in Russia in 2010 
 and the forecast of volcanic SO<sub>2</sub> plumes
 .
