Proposal Title: Study of Electrodynamic Coupling between Ionospheric Layers
ABSTRACT:
High resolution ISR observations of the evening and nighttime E- and F-regions at Arecibo during both "normal"
low-activity periods and during an active spread-F event reveal apparent electrodynamic links between the
low-lying layers, ion-rain, and the spread-F instability process. This coupling is manifested as "ion rain" structures
extending from the base of the F-region onto the underlying intermediate layer and down to 100 km during
intensive spread-F events. We propose measuring horizontal structure and plasma drifts at the highest possible
resolution throughout the 80-450 km altitude region
