Seasonal frozen ground area on the Tibetan plateau has particular land surface condition with frozen ground and patchy snow distribution. The existing satellite microwave remote sensing was therefore unable to estimate the snow quantity exactly. An evaluation method of snow area proportion based on AVNIR-2 and MODIS over the seasonal frozen ground area on the Tibetan plateau was therefore devised in this study, and it was introduced to estimated snow depth based on Tsutsui and Koike (2012) 's snow estimation method. In the result, we were able to compare the estimated snow depth with the in situ snow depth data, and the relatively good agreement was recognized. Simultaneously the availability of the Tsutsui and Koike (2012)'s snow estimation method and the evaluation method of snow area proportion based on AVNIR-2 and MODIS was recognized.
