Abstract: In recent years, there has been increasing interest in the application of Kalman filter systems to atmospheric data assimilation. One important aspect of any data assimilation system is its filtering properties. This is ...

Abstract: A Kalman filter system designed for the assimilation of limb-sounding observations of stratospheric chemical tracers, which has four tunable covariance parameters, was developed in Part I of this two-part paper. The ...

Abstract: The first part of this two-part article describes the formulation of a Kalman filter system for assimilating limb-sounding observations of stratospheric chemical constituents into a tracer transport model. The system is ...
