Heights of SuperDARN F region echoes estimated from the analysis of HF radio wave propagation
Description (Dublin Core)
Tomographic estimates of the electron density altitudinal and latitudinal
distribution within the Hankasalmi HF radar field of view are used to
predict the expected heights of F region coherent echoes by ray tracing and
finding ranges of radar wave orthogonality with the Earth magnetic field
lines. The predicted ranges of echoes are compared with radar observations
concurrent with the tomographic measurements. Only those events are
considered for which the electron density distributions were smooth, the
band of F region HF echoes existed at ranges 700–1500 km, and there was a
reasonable match between the expected and measured slant ranges of echoes.
For a data set comprising of 82 events, the typical height of echoes was
found to be 275 km.
