全国天气雷达组网反射率产品

产品包括组网组合反射率、混合扫描反射率、三维反射率。组合反射率为垂直方向上雷达观测的最大反射率，用于初生对流回波及成熟雷暴的监测；混合扫描反射率根据波束遮挡情况选择不同仰角的数据拼接得到，用于定量估测降水及监测低层仰角回波的发展动态；三维反射率为等高面上的反射率因子，用于监测特定高度的回波范围、强度、演变情况。

The products include grid-based composite reflectivity, hybrid-scan reflectivity, and three-dimensional reflectivity. Composite reflectivity is the maximum reflectivity observed by radar in the vertical direction, which is used for monitoring nascent convective echoes and mature thunderstorms; hybrid-scan reflectivity is obtained by stitching data from different elevation angles based on beam blockage conditions, and is applied to quantitative precipitation estimation and monitoring the development dynamics of low-elevation echoes; three-dimensional reflectivity refers to the reflectivity factor on contour planes, which is utilized to monitor the echo range, intensity and evolution at specific altitudes.
