Based on medium resolution satellite remote sensing(RS) data Landset ETM and OLI from 2013 to 2014, the authors conducted snow cover RS monitoring in the west of Ngari area in northern Tibet. Changing characteristics of snow-covered area over the two years were summed up by utilizing the statistical calculation method. Using the air temperature data, the authors studied in detail the corresponding rule between the snow-covered area changes and the air temperature value changes. Some conclusions have been reached: Every year the maximum period of the snow-covered area is from January to February, about 10 days before or after the beginning of spring. The maximum percentage of the snow-covered area reaches 80.82 percent. The minimum period of the snow-covered area is August, about 10 days before or after the beginning of autumn. The minimum percentage of the snow-covered area is only 0.77 percent. Annually, the decrease from the maximum percentage of the snow-covered area to the minimum percentagelasts for 6-7 months, which is a relatively gradual process. In the second stage, there is a fluctuation percentage of the snow-covered area for about 4-5 months. At last, the increase from the fluctuation percentage to the maximum percentage is a relatively drastic process lasting for 1 month or so.
