| Outline of Final Research Achievements |
We conducted tropospheric chemistry reanalysis calculations by assimilating multiple data sets from multiple satellite sensors. The reanalysis calculations were conducted using three different global chemical transport model and an ensemble Kalman filter technique that simultaneously optimises the chemical concentrations of various species and emissions of several precursors. The optimisation of both the concentration and the emission fields is an efficient method to correct the entire tropospheric profile and its year-to-year variations, and to adjust various tracers chemically linked to the species assimilated. Using the multiple chemical transport models, we demonstrated the importance of forecast model performance on tropospheric chemistry data assimilation.
