A network observation of traveling ionospheric disturbances during the annular eclipse of September 23, 1987
Abstract
Simultaneous three-station measurements of TEC and HF CW Doppler frequency shifts, and a single rapid-run ionosonde observation were made during the annular eclipse of September 23, 1987 in Wuhan, China. The fast fluctuation components of the TEC measurements are used to describe the TIDs related to the eclipse and to determine the horizontal phase velocity of TIDs at ionospheric heights near the F2-peak region. The Doppler curves are used to determine the horizontal phase velocity of the TIDs at a height of about 200 km in the F-region. Also, the height evolution of the TIDs are studied using the ionosonde observations.
