英文摘要: The bottom-type irregularity scattering layer (BSL) that can appear in the ionospheric F region bottomside has been observed generally after sunset, serving as a possible telltale of equatorial spread F (ESF). Using simultaneous multibeam radar measurements over two low-latitude stations, Sanya (18.3 degrees N, 109.6 degrees E; dip latitude 13 degrees N) and Fuke (19.3 degrees N, 109.1 degrees E; dip latitude 14 degrees N) in China, we report, for the first time, a thin BSL that initially occurred at presunset (similar to 1720 LT), much earlier than the occurrence of BSL generated from the equatorial plasma shear vortex-driven instability. The presunset BSL was situated around 225km altitude and continued to exist until the appearance of ESF plumes after sunset (similar to 1930 LT). Interestingly, the Doppler velocities of the presunset BSL echoes measured by the radar and the F layer virtual heights obtained from the collocated Digisonde measurements over Sanya both show oscillations with a period of about 1 h, suggesting a close link between the occurrences of the BSL and of F region plasma density large-scale wave structure before sunset. These observations could imply an important role of gravity waves in the generation of the presunset F region bottom-type irregularities.
