Abstract :
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 of the sea surface temperature data obtained by FY2-C satellite. For comparing satellite data with grid data, this method can reduce the spurious error resulted from changed pixel characteristics during downscaling or upscaling. For comparing satellite data with station data, this method can give relatively accurate results while requiring less precise spatial matching.
