                         behavior of the mesopause Sodium (Na) and Potassium (K) layers 
                         simultaneously observed by a dual beam LIDAR at lower latitude in 
                         the Southern Hemisphere. We analyze these two alkali metal layers 
                         from November 2016 to April 2018 measured at S{\~a}o Jos{\'e} 
                         dos Campos (23.1°S, 45.9°W). These metal layers show the following 
                         annual mean characteristics: K abundance ranges from 2.5 to 20x107 
                         atoms per cm2 , with the layer peak around 90.7 km and width 
                         varying from 6 to 11 km; Na abundance varies from 15 to 120x108 
                         atoms per cm2 , its peak is around 92 km with the layer width 
                         varies from 5 to 19 km. The wider Na layer occurs on October which 
                         is the most abundant Na density month. The centroid for both 
                         metals, K and Na, varies little through the year and the K layer 
                         is on average 1.3 km lower. Seasonal variation in the Na density 
                         shows semiannual variation with maxima at May and October while an 
                         annual variation with maximum around winter can be observed on the 
                         K.",
