SUMMARY: Modelling and data assimilation of reactive gases at the European
  Centre for Medium-Range Weather Forecasts. - Dr Johannes Flemming\, ECMWF

DESCRIPTION:Forecasting and data assimilation of atmospheric composition h
 ave become important activities at ECMWF as part of the MACC project. MACC
  makes daily global forecasts and has produced a  re-analysis of atmospher
 ic composition (2003-2010). Both data sets are freely available and can be
  used for campaign support\, provision of boundary conditions\, climatolog
 ical studies or model evaluation.  We present the modelling system for rea
 ctive gases and how it is used in the assimilation of satellite observatio
 ns. We will discuss the benefit of data assimilation using two examples: t
 he forecast of the severe pollution caused by fires in Russia in 2010 and 
 the forecast of volcanic SO<sub>2</sub> plumes.
