Abstract
MOCAGE is the new atmospheric chemistry model of Météo-France. Among the model features is the possibility to consider both the troposphere and lower stratosphere, as well as to treat several levels of nested domains. A comparison of a model simulation with MOZAIC observations shows a good agreement between the two. However, in order to further improve the realism of the simulations, data assimilation can be employed. We show that a non-local technique brings an improvement in the model that lasts for over four days, the time needed to have an almost global coverage with MOZAIC. This opens the possibility of conducting long model simulations, typically of the order of one year, with a realistic Upper Troposphere — Lower Stratosphere region.
