Paper Abstract

The channel-to-channel co-registration of a satellite imaging system is an important performance metric that has a direct impact upon the reliability of the imager’s quantitatively-derived products. In this work, standard full-disk image data is used to measure the on-orbit channel-to-channel co-registration of the infrared channels of several GOES Imagers at a sub-pixel level. This is accomplished with two separate methods, one of which furthers preliminary research by Wu et. al.1 using GOES-8 and 9 spatial-spectral brightness temperature gradients, the other of which uses a statistical approach. The diurnal, seasonal, and long-term co-registration behavior is analyzed.
