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。

This product constructs a highly structured specialized disease dataset strictly in accordance with standardized procedures, based on the disease-specific diagnosis and treatment guidelines and clinical pathways for severe pneumonia. This dataset provides great convenience and practicality for data users, helps improve the quality and efficiency of clinical research, offers an open, shareable and scalable standard dataset for severe pneumonia, and delivers robust data support and decision-making basis for researchers, clinicians and medical decision-makers.
