A Basic Study of Short Term Forecasting Methods of Snowfall and Road Surface Temperature Using Intelligent Visibility Meter


In this research, we aimed to examine the possibility of very short term (to 3 hours later) forecasting of snowfall and road surface temperature by using the observation data of the Intelligent Visibility Meter which has functions to calculate precipitation type and intensity. As a result, we cleared that forecasting precision can be improved by our newly developed method.
