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

我们开发了一套新的低层降雪廓线测量系统。利用3台小型k波段多普勒雷达测量了雷达反射率因子和光谱。同时捕获降雪颗粒的图像，测量其大小和下降速度。利用积雪颗粒图像，比较了雷达的雷达反射率因子与后向散射截面之和。

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.
