中文摘要：

将直方变差图中的“驻点”理论引入卫星产品质量验证中，用于解决不同资料对比中的空间配准问题。提出了直方变差图理论用于卫星资料质量检验中驻点、边界点的定义以及应用原理，以中国风云2号C星海面温度产品为例，对这种方法进行了应用试验，结果表明，可以减少卫星产品检验空间配准过程中由于降尺度（downscaling）或升尺度（upscaling）导致像元性质改变而引入的伪误差；通过卫星资料与离散常规观测资料的比对，可以不严格进行空间配准，也可得到相对准确的精度检验结果。

英文摘要：

A new method for spatial matching of data with different resolution was proposed by introducing the concept of standing and contour pixels in histo-variogram theory, and was examined in quality validation using the sea surface temperature data obtained by FY2-C satellite. For comparing satellite data with grid data, this method can reduce the spurious error resulting from changed pixel characteristics in downscaling and upscaling. For comparing satellite data with station data, this method can give relatively accurate results while requiring less precise spatial matching.
