| Outline of Final Research Achievements |
Methods to observe snow accumulation and melting are developed for use in places where snow observation data are difficult to collect, for example, in mountainous and forested areas where few observation studies have been performed. First, the snow temperature profile method is used using small temperature loggers, and improvements are made for increasing the method's practicality. Moreover, a new device is developed to judge the precipitation phase (rain or snow) using sound. Finally, snow depth is measured at numerous points in a forested area, and the relation between snow depth, topographic conditions (elevation and slope direction), and forest conditions (canopy) is investigated.
