摘要(Abstract)：

多源降水产品在过去十几年来得到了广泛的应用,然而在数据缺失区其可靠性检验的难度较大。采用Triple-Collocation(TC)方法可以在未知真值的情况下,对三组相互独立的产品进行交叉评估。基于TC方法,综合评估了卫星遥感产品、再分析产品与地面实测数据集在中国区域的不确定性。研究所选空间分辨率为0.25°,时间分辨率为日尺度,数据选用时段为2013—2015年。首先,在中国南方对TC方法进行可靠性验证。通过与传统方法所得结果(相关性系数CC与均方根误差RMSE)对比,相对偏差仅为4.5%与3.0%,而后将方法应用于整个中国大陆区域(除台湾地区),并重点关注青藏高原数据缺失区。结果显示:在卫星产品中,IMERG整体表现最优;在青藏高原无台站网格点上,IMERG与ERA-interim所得平均CC分别为0.63与0.61,略优于地面实测数据集(0.58),这表明卫星遥感产品与再分析产品在青藏高原区域具有一定的优势和应用潜力;实测数据在台站稀疏区域的高不确定性也得到了进一步验证。研究成果证明了TC方法在中国大陆区域的适用性和可靠性,为数据缺失区的降水产品评估提供新的思路和方法。
