Variations in Thermosphere during the 2018 SSW Event at Beijing and Wuhan Stations

SSW: temporal variations in stratospheric conditions prior to, during and after the SSW2018 from January 20 to March 21 (DOY 20 - DOY 80), 2018. First column: year; second volumn: DoY; third volumn: stratospheric temperature at 10h Pa at 60°N; fourth volumn: stratospheric temperature at 10h Pa between 60°N and 90°N; fifth volumn: velocity of zonal wind.average: average values between 1979 and 2017. first volumn: stratospheric temperature at 10h Pa at 60°N; second volumn: stratospheric temperature at 10h Pa between 60°N and 90°N; third volumn: velocity of zonal wind.F107andAp: temporal variations of F107 index and Ap index. First volumn: DoY; second volumn: local time; third volumn: F107 index; fourth volumn: Ap index.Tex_Beijing/Den_Beijing: retrieved Tex and corresponding neutral density at Beijing; DoY:20-80;LT:9:0.24:16;Tex_Wuhan/Den_Wuhan: retrieved Tex and corresponding neutral density at Wuhan; DoY:20-80;LT:9:0.24:16;Tex_Beijing_MSIS/Tex_Beijing_GCITEM: calculated Tex by empirical model NRLMSISE-00 and theoretical model GCITEM-IGGCAS at Beijing; DoY:20-80;LT:9:0.24:16;Tex_Wuhan_MSIS/Tex_Wuhan_GCITEM:calculated Tex by empirical model NRLMSISE-00 andtheoretical model GCITEM-IGGCAS at Wuhan; DoY:20-80;LT:9:0.24:16;Neden_Beijing/Wuhan:electron density observed by ionosondes at Beijing/Wuhan below 200 km, line: local time, volumn: altitude;date_obs_Beijing/Wuhan: local time of observed electron density at Beijing/Wuhan.
