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: Recent developments in the field of data assimilation have Pointed to variational analysis (essentially least- squares fitting, of a model solution to observed data) using the adjoint method as a new direction that holds ...

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 ...
