摘要：
An ensemble Kalman filter data assimilation system has been coupled to the Danish Eulerian Hemispheric Model (DEHM), a hemispheric-scale, offline, chemistry-transport model. We present an evaluation of the performance of the assimilation system in the framework of an Observing System Simulation Experiment (OSSE). This involves assimilating "pseudo-observations" derived from a reference simulation, and then comparing the assimilation run with the reference run. We focus on nitrogen dioxide and the pseudo-observations are generated to mimic the spatial/temporal pattern of retrievals from the Ozone Monitoring Instrument.
