Road weather observations: vt4 Northern Lights 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运输局（Finnish Transport Agency）道路气象系统生成的道路沿线气象实况数据。道路沿线共设有近500座道路气象站，可开展气象与道路气象双重观测，其中绝大多数站点分布于芬兰沿海区域与芬兰南部地区。道路气象站每10至15分钟采集一次数据：路面传感器用于监测路面状态，气象传感器则用于采集当前气象实况。受布设位置特性影响，道路气象站的气象传感器数据可靠性，以及站点间数据的可比性，均逊于芬兰气象研究所（Finnish Meteorological Institute）设于气象代表性最佳点位的常规气象观测站。由于道路气象站的核心观测重点为道路相关气象指标，因此其布设方案与常规气象站存在显著差异。
