AbstractA double-laser beam lidar was successfully developed to simultaneously measure K and Na layers at Beijing (40.6 degrees N, 116.2 degrees E) in 2010. Statistical analysis of the parameters of sporadic K (K-s) and sporadic Na (Nas) layers was performed over 2years of lidar data, and different characteristics of them were found. The average K-s occurrence (2.9%) was lower than that of Nas (5.9%); the Nas occurrence had a maximum (19.3%) in May-June months and a minimum (1.6%) in January-February months, while the K-s occurrence had a maximum (4.9%) in January-February months and a minimum (1.0%) in September-October months; most K-s peaks tended to occur around 93km, which was similar to 2km lower than that of Nas (similar to 95km); the K-s peak density was often at least 1 order of magnitude lower than that of Nas; notably, two K-s with high peak densities (>1000cm(-3)) were observed, which were much higher than K density (15-300cm(-3)) reported before. The ascending time of K-s was often longer than its descending time, but an opposite trend occurred for Nas. During the 152 cases of joint observation for the K and Na layers, 21% (32/152) were cases in which K-s and Nas events simultaneously occurred, while 79% (120/152) were cases in which only one layer (K or Na) exhibited a strong K-s or Nas.
