Road weather observations: vt7_Virolahti_Mattila_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.该数据集包含芬兰运输局（Finnish Transport Agency）道路气象系统采集的道路沿线现行气象状况相关信息。道路沿线共设有近500座气象及道路气象观测站，其中绝大多数站点位于芬兰南部沿海区域。道路气象站每10至15分钟便会通过各类路面传感器采集路面状态数据，并借助气象传感器采集当前气象数据。由于道路气象站的选址特点，其气象传感器数据的可靠性以及站点间数据的可比性，均逊于芬兰气象研究所（Finnish Meteorological Institute）设于气象代表性最优点位的常规气象观测站。鉴于道路气象站的核心职能为气象测量，其站点布设方法也与常规气象站存在差异。
