The dates and times below are subject to change. Local 10 Position Coordinated radar and optical observations. Radar measurements taken in 10 directions will allow estimation of spatial gradients.
Clear weather is required.
Coordinated Radar and Daysky Optical Observations. Clear weather is required. Radar measurements to investigate anomalous nighttime electron temperature and density variations from 200 km into the topside ionosphere. The experiment uses a sequence of pulse lengths to ascertain local conditions with the zenith antenna. Alternating 8-point MISA measurements at two elevation angles and at S, W, N, and E compass positions provide latitudinal and longitudinal context for the local variations seen.
