摘要
Abstract
This paper uses the data of the all-sky meteor radar in Mohe and Wuhan stations from 2012 to 2022 to estimate the atmospheric temperature at 90 km based on the linear relationship between the full width at half maximum(FWHM)of the meteor height distribution and the temperature.Since the fitting parameters were found to be almost constant when linearly fitting the data from year to year,this paper uses the parameters summarized over time to fit the temperature and compares it with the conventional gradient method.The results show that the temperature measured by the FWHM method is closer to that of the Aura satellite,where the correlation coefficient and the mean error are better than those of the gradient method.Moreover,the FWHM method fits better at the higher latitudes Mohe station than the lower latitudes Wuhan station.All in all,it is feasible to use the FWHM method to estimate the atmospheric temperature at mesopause at Mohe and Wuhan stations.Besides,this paper verifies that latitude can affect the error of the FWHM method,where the error of the FWHM method is smaller at higher latitude.关键词
