Extension of an Empirical Electron Flux Model From 6 to 20 Earth Radii Using Cluster/RAPID Observations
Taylor, M. G. G. T.; Henderson, M. G.; Rodriguez, J. V. +1 more
An existing empirical model of the electron fluxes at geosynchronous orbit is extended radially outward in the equatorial plane to 6-20 Earth radii (RE) using observations from the Research with Adaptive Particle Imaging Detectors (RAPID) instrument on the Cluster spacecraft. The new model provides electron flux predictions in the energ…
Global Diagnostics of Ionospheric Absorption During X-Ray Solar Flares Based on 8- to 20-MHz Noise Measured by Over-the-Horizon Radars
Lester, M.; Marchaudon, A.; Marcucci, M. F. +9 more
An analysis of noise attenuation during 80 solar flares between 2013 and 2017 was carried out at frequencies 8-20 MHz using 34 Super Dual Auroral Radar Network radars and the EKB ISTP SB RAS radar. The attenuation was determined on the basis of noise measurements performed by the radars during the intervals between transmitting periods. The locati…
Development of a 3-D Plasmapause Model With a Back-Propagation Neural Network
He, Fei; Lei, Jiuhou; Zhang, Xiao-Xin +2 more
Several empirical models have been previously developed to study the characteristics of the global plasmasphere. A three-dimensional solar wind-driven global dynamic plasmapause model was developed in this study using a back-propagation neural network based on multisatellite measurements. Our database contains 37,859 plasmapause crossing events fr…
Generalized Additive Modeling Combined With Multiple Collinear for ICME Velocity Forecasting
Ji, H. S.; Wang, M.; Lu, J. Y. +5 more
One of the main issues of space weather is the timely prediction of disturbed solar wind parameters at L1, especially caused by Coronal Mass Ejection (CME). Using the data from 170 front halo, flare-associated CMEs, and in-site solar wind data, an analysis of the Interplanetary Coronal Mass Ejection (ICME) peak velocity at L1 related to associated…
