The EPS/MetOp RAO project AGORA aims at exploiting chemical observations from GOME-2 and IASI by means of Data Assimilation, Chemical Transport Modelling and General Chemistry Circulation Modelling. Focus will be on global monitoring and forecasting of ozone and ozone related species. Therefore, two data assimilation systems will be applied. For continuation of GOME-1 and reanalysis purposes a well established sequential assimilation scheme will be used. It is based on an optimal interpolation approach using advanced assimilation parameters like error propagation and Chi2 monitoring and a CTM. For ozone analysis and forecasting the 4D-Var data assimilation system SACADA will be applied. It allows a consistent chemical analysis for both, conservative and reactive species. The underlying GCCM of SACADA enables to perform global chemical forecasts of the stratosphere. The system is currently prepared for routine operation at DLR with direct interface to the O3 SAF Level 2 products. The global analyses and forecasts of ozone and related species will be operationally disseminated via the World Data Center for Remote Sensing of the Atmosphere (http://wdc.dlr.de)
