Abstract:
In order to apply the snow depth data effectively to disaster prevention and reduction, more than 200 sets of automatic snowdepth observation instruments were deployed by the Zhejiang Weather Service in recent years In this paper, the performance of these instruments during routine operation is assessed Problems in instrument structure, snowboard material, installation way, soil frost, and others are examined, and the reasons are analyzed Meanwhile, a quality control method of the snowdepth data based on the hourly variation is put forward and tested in actual snowfall Suggestions for improving the technical specifications of snowdepth observation are also proposed Analysis results indicate that although there are some problems, the automatic snowdepth observation instrument is capable of reflecting the snow cover continuously and obtaining multiple real time data, which has significant advantages in timeliness and precision comparing with manual measurements
