A coupled dynamic chemistry transport model and assimilation system

Summary: The first result of the project is a system able to assimilate spaceborne stratospheric ozone data into a DCTM model. Its exploitation is especially linked to research topics on stratospheric ozone trends and dynamics. Further this system could be distributed to external users for similar activities under license conditions. As stratospheric ozone measurements (from any sources) are sparse in time and space, the assimilation technique allows to refine the analysis by performing an optimal interpolation in the four dimensions. This is the major innovative feature of the present result. The system is today operational and as such has been also derived as an executable tool (see result 2). Expected benefit and use rank from the validation campaign optimization for new spaceborne sensors to the improvement of DCTM code by analysis of systematic discrepancies (especially in chemistry modeling and tropo/mesospheric boundary conditions) and long term monitoring. The system will be a development platform for data from other potential instruments in close co-operation with the other MSDOL members and extended partnership.
