2001-2010年北半球雪深数据集

此数据集为2001-2010年10年的北半球逐日雪深数据，数据覆盖范围为：0-86oN，180OW-180OE。该数据集结合积雪过程模型和积雪微波辐射传输模型，并吸收地面观测站点资料对雪深进行提取，引入森林覆盖率因子降低森林对雪深反演的影响，利用集合卡尔曼滤波方法综合卫星观测的微波亮度温度和模拟的亮度温度对积雪参数进行优化；在森林地区通过森林覆盖率降低森林的影响，获得北半球雪深数据集。其空间分辨率为0.25o*0.25o。数据大小共13.5G。

This dataset consists of 10-year (2001–2010) daily snow depth data over the Northern Hemisphere. Its spatial coverage spans 0°–86°N and 180°W–180°E. It integrates the snow process model and the microwave radiative transfer model for snowpack, incorporates ground-based observational station data to derive snow depth, introduces the forest cover factor to alleviate the impact of forest cover on snow depth retrieval, and employs the ensemble Kalman filter to optimize snow parameters by fusing satellite-observed microwave brightness temperatures and simulated brightness temperatures. By accounting for forest cover effects in forested areas using forest cover information, the finalized Northern Hemisphere snow depth dataset is generated. The spatial resolution of the dataset is 0.25° × 0.25°, and the total data volume is 13.5 GB.
