  1. Ionospheric weather forecasting using the LETKF

    23 Mar 2015 | | Contributor(s):: Juan Durazo

    We track the three-dimensional global distribution of electron density in the ionosphere using theLocal Ensemble Kalman Filter (LETKF) and the Thermosphere-Ionosphere-Electrodynamics GlobalCirculation Model (TIEGCM) by assimilating globally distributed electron density profiles. TheTIEGCM is a...

  8. Extending the square root method to account for model noise in the ensemble Kalman filter

    25 Feb 2015 | | Contributor(s):: Patrick Raanes

    Presented by Patrick Raanes on 2-18-2015 Abstract:A novel approach to account for model noise in the forecast step of the Ensemble Kalman filter (EnKF) is proposed.  The core method is based on the approach of the analysis step of ensemble square root filters (ETKF), and...
