Abstract

This paper discusses the SRCA spatial calibration for the band centroid shift along-track. It is the second part of spatial calibration, which is for along-track. Next is a discussion of the linear range of weighted Y, which is the moment arm in the centroid computation, and the effect of MODIS/SRCA magnification change on the Y value. Also described is the relative calibration between channels under different environments and by different instruments. An overall summary of uncertainty sources and spatial calibration accuracy are presented.
