RISDevelopment of a Hybrid En3DVar Data Assimilation System and Comparisons with 3DVar and EnKF for Radar Data Assimilation with Observing System Simulation Experiments
Publisher: American Meteorological Society
Abstract: AbstractA hybrid ensemble?3DVar (En3DVar) system is developed and compared with 3DVar, EnKF, ?deterministic forecast? EnKF (DfEnKF), and pure En3DVar for assimilating radar data through perfect-model observing system ...
Direct Assimilation of Radar Reflectivity Data Using 3DVAR: Treatment of Hydrometeor Background Errors and OSSE Tests
Publisher: American Meteorological Society
Abstract: Despite the well-known importance of background error covariance in data assimilation, not much study has been focused on its impact on the assimilation of radar reflectivity within a three-dimensional variational (3DVar) ...
