Road weather observations: vt12_Iitti_Mankala

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.本数据集收录芬兰运输局道路气象系统生成的道路沿线实时气象状况相关数据。芬兰道路沿线共部署近500座可同时开展气象观测与路面气象监测的道路气象站，其中多数站点位于芬兰南部与沿海区域。道路气象站通过各类路面传感器采集路面状况数据，并借助气象传感器采集实时气象信息，每10至15分钟上传一次观测数据。由于道路气象站的选址特性，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设置于气象代表性最优区域的常规气象观测站。道路气象站以路面状态与气象观测为核心任务，因此其选址方式与常规气象站存在差异。
