Tracking heliospheric disturbances by interplanetary scintillation [PDF]
Nonlinear Processes in Geophysics, 2006 Coronal mass ejections are known as a solar cause of significant geospace disturbances, and a fuller elucidation of their physical properties and propagation dynamics is needed for space weather predictions.

Observations of long-lived solar wind streams during 1990-1993 [PDF]
Annales Geophysicae, 1995 Interplanetary scintillation (IPS) can be used to identify changes in solar wind parameters over a wide range in heliographic latitude and elongation and constrain models of its large-scale structure, velocity and density.
