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。

Due to the reflection characteristics of snow and cloud, the use of optical remote sensing to monitor snow cover is seriously disturbed by weather. This product is based on the most commonly used cloud removal algorithm, using MODIS daily snow products and passive microwave data AMSR-E snow water equivalent products to develop the daily cloudless snow products in the Qinghai Tibet Plateau, with high accuracy. The product has important use value for real-time monitoring the dynamic changes of snow cover on the Qinghai Tibet Plateau.
