| Abstract: | The formula for the inversion of electron density from the power profiles is described firstly. Then some preliminary measurements of the power profile are presented. Combining the measurement of the collocated ionosonde, some typical space weather characteristic including the wave-like disturbance in night, the location of the northern crest of the equatorial ionospheric abnormal, the enhancement of electron density after sunset, and the ionospheric variation during the geomagnetic storm are investigated. The above results help us understand the ionospheric space weather characteristic in Qujing and show the good capability of Qujing ISR in the observation and research in the low-latitude ionospheric abnormal region of China. |
