    A New Model for Nowcasting the Aviation Radiation Environment With Comparisons to In Situ Measurements During GLEs by A. D. P. Hands, F. Lei, C. S. Davis, B. J. Clewer, C. S. Dyer, K. A. Ryden

    Published 2022-08-01
    “…The Model for Atmospheric Ionising Radiation Effects (MAIRE+) uses multiple data sources to characterize primary GCR and GLE particle spectra and combines these with precalculated geomagnetic and atmospheric response matrices to predict particle fluxes from ground level to 20 km altitude across the entire globe. Two European neutron monitors (located at Oulu in Finland and Dourbes in Belgium) are used as the primary indicators of GLE intensity in order to maximize accuracy over UK airspace. …”

    Real‐Time Thermospheric Density Estimation via Two‐Line Element Data Assimilation by David J. Gondelach, Richard Linares

    Published 2020-02-01
    “…Three different models are developed based on density data from the TIE‐GCM, NRLMSISE‐00, and JB2008 thermosphere models and are valid from 100 to maximum 800 km altitude. Using the models and TLE data, the global density is estimated by simultaneously estimating the density and the orbits and ballistic coefficients of several objects using a Kalman filter. …”
