英文摘要	A dual-wavelength resonance fluorescence lidar facility, operating at 770nm and 589 nm, was set up in the midlatitude of East Asia, Beijing (40.41(o)N, 116.01 E-o), to detect the upper atmospheric potassium and sodium layers simultaneously. This fluorescence lidar system has been operational for 220 nights, clocking 1250 h in total from November 2010 to October 2011 and May 2013 to April 2014. The observations reveal that the potassium layer shows considerable semiannual seasonal variations. Specifically, the column and peak densities vary semiannually with maxima in winter and summer. The centroid height displays semiannual variation, reaching maxima in spring and autumn. The RMS width has a slight semiannual seasonality with maxima in July and December. The seasonal behavior of the potassium layer in Beijing is similar to that in other potassium lidar sties. However, the unexpected difference is that the column and peak densities of the potassium layer are extremely large in winter, compared to the maximum values in summer.
