Road weather observations: st103_Hki_Vuosaaren_tunneli_O

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.本数据集包含芬兰运输管理局（Finnish Transport Agency）道路气象系统采集的道路沿线当前气象状况相关信息。该系统沿道路布设了近500个道路气象站（road weather station），可同时开展常规气象与路面气象观测，绝大多数站点坐落于芬兰沿海区域与南部地区。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当前气象要素，每10至15分钟上传一次观测数据。由于道路气象站的布设点位特性，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（Finnish Meteorological Institute）设在气象代表性最优区域的常规气象观测站。道路气象站的核心观测目标为路面相关气象要素，因此其布设方式与常规气象观测站存在差异。
