Road weather observations: vt7_Porvoo_Ernestas_2

The dataset contains information on the prevailing weather conditions on the roads produced by the Finnish Transport Agency's road weather system. There are nearly 500 weather and weather-observing road weather stations along the roads. Most stations are located in the coastal region and southern Finland. Road weather stations provide data every 10-15 minutes from various road surface sensors on road surface conditions and meteorological sensors on the prevailing weather. Due to the location of the road weather stations, the reliability of the weather sensor data and the comparability of the data between the stations are weaker than with the weather observation stations of the Finnish Meteorological Institute, which are located in the most meteorologically representative locations. At road weather stations, the main focus is on weather measurement and the stations are therefore positioned using different methods than the weather stations.本数据集收录由芬兰运输局（Finnish Transport Agency）道路气象系统生成的道路沿线实况气象相关数据。该系统沿线共布设近500个兼具气象观测与路面状态监测功能的道路气象站，其中多数站点分布于芬兰沿海地区与芬兰南部。道路气象站通过各类路面传感器采集路面状况数据，同时依托气象传感器获取实时气象数据，每10至15分钟更新一次观测数据。由于道路气象站的选址限制，其气象传感器数据的可靠性以及站点间数据的可比性，均弱于芬兰气象研究所（Finnish Meteorological Institute）的气象观测站——后者的选址均为最具气象学代表性的区域。道路气象站以气象与路面状态测量为核心观测目标，因此其选址方法与常规气象站存在显著差异。
