高速公路沿线灾害性天气实况告警

产品融合气象站实况观测数据、高速公路路网信息，得到基于GIS的高速公路沿线气象实况监测数据，进一步结合不同气象条件对高速公路安全的影响程度，划分四个影响等级，分别为较小影响、较高影响、高影响、极高影响，生成分等级、分要素的实况告警产品，时间分辨率为10分钟，空间分辨率为1km。

This product integrates real-time observational data from weather stations and highway network information to generate GIS-based real-time meteorological monitoring data along expressways. Furthermore, four impact levels are classified based on the impact extents of different meteorological conditions on highway safety, namely minor impact, relatively high impact, high impact, and extremely high impact. Real-time warning products categorized by impact level and meteorological element are then produced, with a temporal resolution of 10 minutes and a spatial resolution of 1 km.
