Road weather observations: vt6_Joensuu_Pekkalan_ilta_Opt

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局（Finnish Transport Agency）道路气象系统生成的道路沿线盛行气象状况相关数据。该系统沿道路共布设近500个道路气象站（road weather station），可开展气象及道路气象观测工作。多数站点位于芬兰南部及沿海区域。道路气象站通过布置在路面的各类路面状况传感器，以及监测盛行气象状况的气象传感器，每10至15分钟采集并传输一次数据。由于道路气象站的布设位置限制，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）布设的气象观测站——后者均选址于最具气象代表性的区域。道路气象站的核心功能聚焦于气象与路面状况监测，因此其布设方式与常规气象观测站存在显著差异。
