摘　　要：北京2022年冬奥会期间,使用北京超大城市综合观测试验7个站点所布设的毫米波云雷达、微波辐射计和风廓线雷达等新型地基遥感观测设备,通过对温度、湿度、风和云的反射率因子的探测反演,对2022-02-13发生的一次降雪全过程进行监测分析。7个站点能够同时监测到降雪云系的移动情况,与地面气象站的观测结果比对发现降水(雪)过程较为吻合,且具备一定的提前优势。During the Beijing 2022 Winter Olympic Games, a snowfall occurred on February 13,2022 was monitored and analyzed through the detection and inversion of temperature, humidity, wind and cloud reflectance factors by using new-type ground-based remote sensing observation equipment, such as millimeter wave cloud radar, microwave radiometer and wind profile radar, which were deployed at 7 stations of Beijing Megacities Integrated Observation Test.The movement of snow cloud system was monitored by the above 7 stations at the same time.Comparing with the observation results of ground weather stations, it was found that the precipitation(snow) process monitored by ground-based remote sensing observation equipment was consistent, even having a certain advance advantage.
