The Impact of Solar Activity on Forecasting the Upper Atmosphere via Assimilation of Electron Density Data

Geographic latitude and altitude distribution
Friday, August 13, 2021

This study presents a comprehensive comparison of the impact of solar activity on forecasting the upper atmosphere through assimilation of radio occultation (RO)-derived electron density (Ne) into a physics-based model (TIE-GCM) using an ensemble Kalman filter.
