In this study, a methodology of constructing and incorporating potential-vorticity (PV) data into initial conditions of a limited-area model is proposed. This methodology is based on the linear correlation between vertical (100hPa-500hPa) mean PV (MPV) and MetOp/GOME2 total ozone (O3) data. On one hand, a linear regression model is implemented to generate MPV from O3 data. On the other hand, a 3Dvariational method is designed to assimilate MPV pseudo-observations as a first step toward investigating their dynamical impact.
