Abstract:

This document summarizes studies on the morphology of ionospheric structure at high latitudes. The program encompasses both theoretical and experimental investigations into this rapidly developing field. Because of the vast range of scale sizes hundreds of kilometers to centimeters that make up the structure, and the need for time-continuous observations, we employ a diverse set of observational techniques. These include in situ observations from rockets and satellites as well as radio propagation and scattering measurements. Topics include F-Region Cross-Field Diffusion Processes High-Latitude Conductivity and Field Aligned Current Systems Low-Altitude Image Striations Associated with Bottomside Equatorial Spread F--Observations and Theory Irregularity Decay in an Isolated Plasma Bubble Electrical Coupling Effects on the Temporal Evolution of F-Layer Plasma Structure Aurora and Electrojet Configuration in the Early Morning Sector Auroral Zone Conductivities within the Field-Aligned Current Sheets, and K sub P Dependence of Auroral Zone Field-Aligned Current Intensity.
