MEMPSEP II. -- Forecasting the Properties of Solar Energetic Particle Events using a Multivariate Ensemble Approach
Maher A. Dayeh, Subhamoy Chatterjee, Andres Munoz-Jaramillo +3
Solar Energetic Particles (SEPs) form a critical component of Space Weather. The complex, intertwined dynamics of SEP sources, acceleration, and transport make their forecasting ve…
Variability of interplanetary shock and associated energetic particle properties as a function of the time window around the shock
Kimberly Moreland, Maher Dayeh, Gang Li +3
We study the effect of sampling windows on derived shock and associated energetic storm particle (ESP) properties in 296 fast-forward interplanetary shocks using ACE measurements a…
Investigating the IBEX Ribbon Structure a Solar Cycle Apart
Maher A. Dayeh, Eric J. Zirnstein, Pawel Swaczyna +1
A Ribbon of enhanced energetic neutral atom (ENA) emissions was discovered by the Interstellar Boundary Explorer (IBEX) in 2009, redefining our understanding of the heliosphere bou…
Solar Cycle Variation of 0.3-1.29 MeV/nucleon Heavy Ion Composition during Quiet Times near 1 AU in Solar Cycles 23 and 24
B. L. Alterman, Mihir I. Desai, Maher A. Dayeh +2
We report on the annual variation of quiet-time suprathermal ion composition for C through Fe using Advanced Composition Explorer (ACE)/Ultra-Low Energy Isotope Spectrometer (ULEIS…
Spherical Harmonic Representation of Energetic Neutral Atom Flux Components Observed by IBEX
P. Swaczyna, M. A. Dayeh, E. J. Zirnstein
The Interstellar Boundary Explorer (IBEX) images the heliosphere by observing energetic neutral atoms (ENAs). The IBEX-Hi instrument onboard IBEX provides full-sky maps of ENA flux…
On the seed population of solar energetic particles in the inner heliosphere
Nicolas Wijsen, Gang Li, Zheyi Ding +5
Particles measured in large gradual solar energetic particle (SEP) events are believed to be predominantly accelerated at shocks driven by coronal mass ejections (CMEs). Ion charge…
Modelling Solar Energetic Neutral Atoms from Solar Flares and CME-driven Shocks
Gang Li, Albert Y. Shih, Robert C. Allen +5
We examine the production of energetic neutral atoms (ENAs) in solar flares and CME-driven shocks and their subsequent propagation to 1 au. Time profiles and fluence spectra of sol…
