| Abstract: | According to the airglow dais measured at the Shanxi Astronomical Observatory, a quaisi-hourly variation in the thermosphere has been obtained by autocorrelation power spectrum, cross correlation power spectrum and periodogram method.The period is 64.5mis at night. Also, the mechanism of the variation is discussde.The results obtained agree well with Charles Niangoran's results. |
