| 摘 要： | 该文利用NOAA卫星的AVHRR资料的通道3（3.55～3.93 μm）数据中所包含的太阳反射光信息，分析了云和雾中粒子的大小分布状况。把分析结果与地面观测资料相对比，发现具有CH3反射率小值的云中大粒子区与降水区间存在一定的关系，CH3反射率大值区与大雾覆盖区之间具有良好对应性。

| Abstract: | The particle size distributions of cloud and fog are analysed by using the reflected sunlight data from NOAA/AVHRR CH3 (3.55—3.93μm). Compared analysed results with ground observations, it is shown that the area with larger cloud particles at the top of cloud is related to precipitation area, and the area of fog cover is coincided with smaller cloud particles. |
