Road weather observations: Vt5 Siilinjärvi Opt

The dataset contains data produced by the Finnish Transport Agency’s road weather system on the weather and weather on the roads. Along the roads there are almost 500 roads and weather observing the weather. The largest number of stations are located in the coastal region and southern Finland. Road weather stations provide information every 10-15 minutes from different road surface sensors about the conditions on the road surface and the weather from meteorological sensors. Due to the location of the road meteorological stations, the reliability of weather sensor data and the comparability of data between stations is weaker than the data of the Finnish Meteorological Institute’s weather observation stations, which are located in the most meteorologically representative locations. The main focus of road weather stations is the measurement of the weather and the stations are therefore positioned using different methods than weather observation stations.
