Substorm Observations by Sounding Rockets and by Reception of Polar-Orbitting Satellite Data
Comprehensive studies of the polar substorm phenomena could be accomplished by expanding the observation network horizontally by setting arrays of unmanned observatories and vertically by use of balloons, sounding rockets and scientific satellites. For example of the research coordination between gr...

Comprehensive studies of the polar substorm phenomena could be accomplished by expanding the observation network horizontally by setting arrays of unmanned observatories and vertically by use of balloons, sounding rockets and scientific satellites.
