Road weather observations: vt1_Espoo_Nupuri_OptX2

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交通运输局（Finnish Transport Agency）道路气象系统采集的道路沿线气象实况相关数据。该系统沿道路布设了近500座用于气象与路面气象观测的路面气象观测站（road weather station），其中大部分观测站位于芬兰沿海区域与南部地区。路面气象观测站通过各类路面传感器采集路面状况数据，借助气象传感器采集实时气象信息，每10至15分钟上报一次观测数据。鉴于路面气象观测站的布设点位特性，其气象传感器数据的可靠性以及站间数据的可比性，均不及芬兰气象研究所（Finnish Meteorological Institute）布设的常规气象观测站——后者的选址均具备最具代表性的气象学特征。由于路面气象观测站的核心观测目标为路面相关气象参数，因此其选址方法与常规气象观测站存在差异。
