Artificial intelligence unfolding for space radiation monitor data
Daglis, I. A.; Sandberg, I.; Evans, H. +5 more
The reliable and accurate calculation of incident particle radiation fluxes from space radiation monitor measurements, i.e. count-rates, is of great interest and importance. Radiation monitors are relatively simple and easy to implement instruments found on board multiple spacecrafts and can thus provide information about the radiation environment…
Analysis and interpretation of inner-heliospheric SEP events with the ESA Standard Radiation Environment Monitor (SREM) onboard the INTEGRAL and Rosetta Missions
Sanahuja, Blai; Papaioannou, Athanasios; Anastasiadis, Anastasios +6 more
Using two heliospheric vantage points, we study 22 solar energetic particle (SEP) events, 14 of which were detected at both locations. SEP proton events were detected during the declining phase of solar cycle 23 (November 2003-December 2006) by means of two nearly identical Standard Radiation Environment Monitor (SREM) units in energies ranging be…
Shock deceleration in interplanetary coronal mass ejections (ICMEs) beyond Mercury's orbit until one AU
Krupar, Vratislav; Grison, Benjamin; Souček, Jan +4 more
The CDPP propagation tool is used to propagate interplanetary coronal mass ejections (ICMEs) observed at Mercury by MESSENGER to various targets in the inner solar system (VEX, ACE, STEREO-A and B). The deceleration of ICME shock fronts between the orbit of Mercury and 1 AU is studied on the basis of a large dataset. We focus on the interplanetary…
The detection of ultra-relativistic electrons in low Earth orbit
Dammasch, Ingolf E.; Berghmans, David; Dominique, Marie +6 more
Aims: To better understand the radiation environment in low Earth orbit (LEO), the analysis of in-situ observations of a variety of particles, at different atmospheric heights, and in a wide range of energies, is needed.
Methods: We present an analysis of energetic particles, indirectly detected by the large yield radiometer (LYRA) instr…
