Abstract

Snow cloud distribution in the lower atmosphere was observed using two optical lidars (ceilometer) set up at the distance of 3.1 km. Visual display was constructed from two time series data measured by each lidar. The instruments additionally included weather station, to measure wind speed and direction, and snowfall gauge, to calculate precipitation rate. All the data were displayed on the same coordinate system to examine the profiles with time synchronization. Combination of all these instruments and methods will be a potent system for understanding lower atmospheric structure.
