"Past, Present, and Future of Solar-Terrestrial Environment" is the keynote of this session. We share the latest scientific papers to understand how the solar-terrestrial environment changes in various time scales, and discuss the necessary international collaboration projects associated with VarSITI. More specifically, welcomed papers include space climate studies using tree rings and ice cores, cutting-edge observational and modeling studies of geospace, heliosphere and the sun, simulational or statistical studies to predict the future space weather and space climate.

This session cooperates with Project for Solar-Terrestrial Environment Prediction (PSTEP) supported by Grant-in-Aid for Scientific Research on Innovative Areas from MEXT/Japan.
