Multiscale geospace physics in Canada

This chapter reviews the Canadian solar terrestrial science program that is rapidly evolving in both appearance and contents. The new Canadian perspective is based on a keen awareness of the multiscale character of geospace and on a realistic yet innovative outlook, which integrates Canada's strengths into national efforts emphasizing the use of multiinstrument techniques to attack multiscale complexities in problems. It discusses four major sections: a description of the plan to enhance Canada's leadership position in ground-based geospace science, centered on the Canadian Geospace Monitoring program; a description of Canada's latest effort to achieve major breakthroughs in the understanding of geospace transition region dynamics, centered on the Canadian small satellite experiment ePOP; a description of Canada's participations in three major international geospace missions; and a description of two potential new Canadian-led geospace missions.
