三江源MODIS逐日无云积雪面积遥感产品（2000-2019年）

本数据集是基于MODIS数据进行处理和分析后得到，通过改进不同下垫面下的不同积雪提取算法，提高了积雪范围识别精度，同时利用隐马尔科夫去云算法和SSM/I雪水当量结合，最终生成完全无云的逐日积雪面积产品。取值范围： 1：积雪；0 非积雪。空间分辨率为0.005 度（约500m），时间范围是2000年2月24日至2019年12月31日。
数据格式为geotiff，推荐使用Arcmap或python +GDAL打开和处理数据

This dataset is generated via processing and analysis of MODIS data. By optimizing snow cover extraction algorithms adapted for various underlying surfaces, the identification accuracy of snow cover extent is improved. Moreover, it integrates the Hidden Markov Model-based cloud removal algorithm with SSM/I-derived snow water equivalent data, ultimately producing a fully cloud-free daily snow cover area product. Value range: 1 represents snow cover, while 0 represents non-snow cover. Spatial resolution: 0.005 degrees (approximately 500 meters). Time span: February 24, 2000 to December 31, 2019. Data format: GeoTIFF. It is recommended to use ArcMap or Python + GDAL to open and process this dataset.
