An ensemble Kalman filter may be considered for the 4D assimilation of atmospheric data. In
this paper, an efficient implementation of the analysis step of the filter is proposed. It employs …

抄録 Despite the explosive growth of activity in the field of Earth System data assimilation
over the past decade or so, there remains a substantial gap between theory and practice …

We present a data assimilation system to estimate surface fluxes of CO2 and other trace
gases from observations of their atmospheric abundances. The system is based on …

The data assimilation of stratospheric constituents is reviewed. Several data assimilation
methods are introduced, with particular consideration to their application to stratospheric …

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 …

This article presents algorithms for temporal parallelization of Bayesian smoothers. We
define the elements and the operators to pose these problems as the solutions to all-prefix …

Particle smoothers are SMC (Sequential Monte Carlo) algorithms designed to approximate
the joint distribution of the states given observations from a state-space model. We propose …
