Global ozone forecasting based on ERS-2 GOME observations
International audience The availability of near-real time ozone observations from satellite instruments has recently initiated the development of ozone data assimilation systems. In this paper we present the results of an ozone assimilation and forecasting system, in use since Autumn 2000. The forec...

International audience The availability of near-real time ozone observations from satellite instruments has recently initiated the development of ozone data assimilation systems.
