Towards the practical use of remote sensing based analysis on melting snow volume for the purpose of natural resource management

Researches have been made in recent years on the use of remote sensing data for measuring volume of melting snow at cold snowy districts as an important water resources in Japan. One of these methods uses a combination of remote sensing data and a thaw volume calculation model called the degree-day method. In this study, the authors obtained a result that shows that the accuracy of this method can be improved by adding a solar radiation heat correction. The authors calculated the snow melting volume using other remote sensing data, and obtained the conclusion that snow melting volume can be calculated with accuracy
