青藏高原地区MODIS逐日无云积雪产品（2002-2010）

本数据为2002.07.04-2010.12.31青藏高原地区MODIS逐日无云积雪产品。由于积雪和云的反射特性，使用光学遥感监测积雪受到天气的严重干扰。本产品是在综合了目前最常用的去云算法的基础上，利用MODIS逐日积雪产品和被动微波数据AMSR-E雪水当量产品，开发的青藏高原地区逐日无云积雪产品，准确度较高，该产品对实时监测青藏高原雪盖动态变化具有重要的使用价值。

This dataset is the daily cloud-free snow cover product over the Tibetan Plateau from July 4, 2002 to December 31, 2010.
Optical remote sensing-based snow monitoring is severely hampered by adverse weather conditions due to the similar reflective characteristics between snow and clouds. This product was developed by integrating the most widely used cloud removal algorithms, leveraging MODIS daily snow cover products and the passive microwave AMSR-E snow water equivalent products, resulting in a high-accuracy daily cloud-free snow cover product for the Tibetan Plateau. This product holds significant application value for real-time monitoring of the dynamic changes of snow cover over the Tibetan Plateau.
