Based on a detailed study of the spectrum characteristics of snow, cloud and their shadows, in

combination with the situation of snow monitoring researches in China and abroad as well as characteristics of

CBERS, this paper deals with the application of CBERS data to snow monitoring. A method in this aspect is

presented in this paper based on abundant data analyses. The data processing technique and the possible error

sources are also discussed in detail in this paper. Verification of the method was carried out by using the data

obtained from Nagqu in Tibet. The results show that this snow monitoring method is feasible and of high precision.

It can therefore provide a theoretical support for the operation of snow monitoring.
