Session Description In this session, the problem of identifying visible changes on the disk of the Sun and/or its Corona that relate to subsequent changes in the radiation and plasma parameters at Earth is addressed. Of particular interest are studies targeting the recognition of pre-cursors to Coronal Mass Ejections (CMEs) and hard spectrum Solar Energetic Particle (SEP) events. Investigations that involve the use of artificial intelligence locally weighted learning and Bayesian inference to deduce from early SEP development the course of future dose build up are also pertinent.
Missions scheduled to spend extended periods in parking orbits, particularly those that pass frequently through the Earth's radiation belts, require in depth knowledge of the changing local environment and the related development of measures to counteract radiation effects on physical and biological systems. Rigorous comparisons of the results of European, JAXA, Chinese and Russian Models of the terrestrial particle environment when tested using state of the art data sets can provide new insight into risk and risk mitigation in LEO.
