Detailed Description

,利用2008.10.01-2009.04.30吉林省6个气象站台实测逐日积雪深度数据，考虑云覆盖的影响，对MODIS双星逐日合成产品和滑动多日合成进行检验，总体精度分别为47.51%和76.52%，明显高于MODIS原始数据MOD10A1 (34.45% )和MYD10A1(30.57%)，详见：Chen S B, Yang Q, Xie H J et al. Spatio- temporal variations of snow cover in Northeast China on flexible multiday combinations of MODIS snow cover products. Journal of Applied Remote Sensing,2014, 8(1):0844685,东北地区是中国三大稳定积雪区，区域尺度的雪盖时空变化监测对水资源的有效利用和雪灾监测和预警具有重要意义。本数据集在2004-2013年美国地球观测卫星TERRA/AQUAMODIS数据基础上经算法改进，自定义生产MODIS Terra/Aqua双星逐日融合数据(MODISDC) 和滑动多日融合数据(MODISMC) 两种基础数据，并且反演积雪天数(Snow Cover Day, SCD)、积雪初日(Snow Onset Date, SCOD) 和融雪终日(Snow Melting Date,SCMD)三类专题数据。利用气象站台实测逐日积雪深度数据，考虑云覆盖的影响，对MODIS双星逐日合成产品和滑动多日合成进行检验，总体精度分别为47.51%和76.52%，明显高于MODIS原始数据MOD10A1(34.45%)和MYD10A1(30.57%)。
