E Region Coherent Echoes. High resolution observations of E-region coherent echoes using low elevation angle measurements to the north and analysis of raw data records. Geomagnetically disturbed conditions are required. Local 10 Position Coordinated radar and optical observations. Radar measurements taken in 10 directions will allow estimation of spatial gradients.
Clear weather is required.
Incoherent Scatter Coordinated Observation Days. The Wide Coverage experiment will be run. This provides wide latitude coverage, at the expense of a relatively long cycle time. It utilizes single pulses of varying lengths for fixed positions, azimuth scans, and elevation scans. Coordinated Radar and Daysky Optical Observations.
