The development of the measurement system for snowfall profiles in the lowest atmospheric layer

我们研制了一种新的大气最低层降雪廓线测量系统。用三台小型K波段多普勒雷达测量了雷达反射率因子和频谱。同时捕获下落的雪颗粒的图像以测量尺寸和下落速度。将雷达反射率因子与雪粒子图像的后向散射截面积和进行了比较。

We developed the new measurement system for snowfall profiles in the lowest atmospheric layer. The radar reflectivity factor and spectrum were measured using three small K-band Doppler radars. The image of falling snow particles were simultaneously captured to measure size and falling velocity. The radar reflectivity factor of radar was compared with the sum of backscattering cross section using snow particle images.
