                         simultaneously at the South Hemisphere site, Sao JoseŽ dos Campos 
                         (23.1S, 45.9W). Measurements reported here were conducted on two 
                         nights with 3.5 and 8 h of observations in November 2016. On 20 
                         November 2016, sporadic layers in both Na and K layer occurred 
                         above 100 km, and the higher layers corresponded well with 
                         sporadic E (Es) layer. And the density of Na at 100105 km is 
                         higher than that at main layer around 90 km, but K density around 
                         100 km is at least 3 times smaller compared with the K density 
                         around 90 km for the similar period. On 21 November 2016, both 
                         sporadic layers occurred in main layer height with obvious 
                         descending variations with time, which seems like tidal induced. 
                         Notably, the peak K/Na ratio slowly increased with time. And Na 
                         layer and K layer showed different processes along with time with 
                         K density reaching its maximum 1 h later than that of Na. 
                         Correlations of Na/K density, Es, and winds were also discussed.",
