京港澳高速韶关段雨雪冰冻实况预警阈值参数数据产品

“京港澳高速韶关段雨雪冰冻实况预警阈值参数数据产品”是一项基于CLDAS和CMPA系统提供的网格化气温和雨量数据的服务。通过计算过去N小时的累计雨量、日最低气温、日平均气温，并进行网格化数据插值，该产品为特定公路段提供精确的气象实况数据。这些数据包括实时气温、雨量以及能见度等关键信息，用于交通气象预警、道路安全监控和应急响应。预警等级通过与预设阈值参数的比较来确定，并根据高速公路段表转换为分路段预警等级，以支持交通管理部门的决策。数据以Excel格式存储，包含观测时间、站点名称、气温、路面温度、能见度、降雨量和风速等字段。

The Real-time Early Warning Threshold Parameter Data Product for Rain, Snow and Freezing Conditions on the Shaoguan Section of the Beijing-Hong Kong-Macao Expressway is a service based on gridded air temperature and precipitation data provided by the CLDAS and CMPA systems. By calculating the cumulative rainfall over the past N hours, daily minimum air temperature and daily mean air temperature, and performing gridded data interpolation, this product provides accurate real-time meteorological data for the specific highway section. These data include key information such as real-time air temperature, rainfall, visibility and others, which are used for traffic meteorological early warning, road safety monitoring and emergency response. The early warning level is determined by comparing with preset threshold parameters, and converted into segment-wise early warning levels according to the table of highway segments to support decision-making of traffic management departments. The data is stored in Excel format, and includes fields such as observation time, station name, air temperature, road surface temperature, visibility, precipitation and wind speed.
