Impacts of Aeolus horizontal Line‐Of‐Sight (HLOS) wind assimilation on the Korean integrated model (KIM) forecast system

open access: yesAtmospheric Science Letters, 2023
The Korean Integrated Model (KIM) forecast system, based on a hybrid four‐dimensional ensemble‐variational method, was extended to assimilate Horizontal Line‐Of‐Sight (HLOS) wind observations from the Atmospheric Laser Doppler Instrument (ALADIN) on ...

On Two Localized Particle Filter Methods for Lorenz 1963 and 1996 Models

open access: yesFrontiers in Applied Mathematics and Statistics, 2022
Nonlinear data assimilation methods like particle filters aim to improve the numerical weather prediction (NWP) in non-Gaussian setting. In this manuscript, two recent versions of particle filters, namely the Localized Adaptive Particle Filter (LAPF) and

Scale-dependent background-error covariance localisation [PDF]

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2015
A new approach is presented and evaluated for efficiently applying scale-dependent spatial localisation to ensemble background-error covariances within an ensemble-variational data assimilation system.
