“…A study by Cooperative Institute for Meteorological Satellite Studies personnel, as well as Grotenhuis et al, 2 found that the co-registration error between channels 2 (3.9 μm) and 4 (10.7 μm) could be as large as 1 pixel in the east/west direction (or ∼4 km), which is considerably larger than the instrument specification. Characterization of GOES channel to channel coregistration errors was seen as an important problem to solve.…”

“…A major problem for this approach is that it is not always possible to extract features on GOES images due to the presence of clouds, which makes it less reliable for a systematic evaluation of co-registration errors. A recent study by Grotenhuis et al 2 uses an area-based approach that involves calculating the cross-correlation of Earth-viewing pixels in different IR channels. In this approach, one of the two images from different IR channels is resampled using linear interpolation, and the correlation in brightness temperature between the resampled image and the image from the other channel is computed.…”

“…However, even under normal operation of onboard systems, minor inaccuracies in INR may lead to temporal misalignments in TIR bands, which may reach half a pixel or more (Boeing, 2006), in addition to regularly occurring band-to-band misregistration of a smaller magnitude (Grotenhuis et al 2012). In addition, there have been several instances of a major failure of the INR components when image misalignment reached multi-pixel scales, including GOES-10 in 2006 and most recently, GOES-15 star tracker failure in April 2015.…”
