waves into the various ionospheric and magnetospheric resonators and waveguides and into the radiation belts. Presentations by Dennis Papadopoulos, Herbert Carlson, Meers Oppenheim, Paul Bernhardt, and others at the workshop highlighted recent and ongoing investigations to show how active ionospheric heating cause-and-effect experiments help resolve critical geospace problems and test predictive space weather forecasting models.

coupling processes requires quantitative characterization of the three elements involved: the IAR, the ionospheric duct, and the SA/MS coupling. Dennis Papadopoulos informed workshop participants of three examples of recent work at HAARP and EISCAT (European Incoherent Scatter Scientific Association)

ionospheric heating experiments at high latitudes, combined with incoherent and coherent radar measurements of the ionospheric dynamics and with multi-satellite observations of the global magnetosphere configuration during both quiet and extreme solar-wind driving conditions, provide unique opportunities to illuminate this process. Dynamics of the Radiation Belts Dennis Papadopoulos led a discussion at the workshop that included consideration of active experiments and the dynamics of Earth's radiation belts.

HF radar scatter from CMEs has been attempted with minimal success using HAARP transmitting at HF and the Jicamarca radar at VHF frequencies, respectively. Bernhardt believes the new Arecibo HF facility in Puerto Rico is especially suited to attempt radar measurements of the Sun and Moon because of its relatively low latitude.
