Why is the HRV image split?
The downlink from the satellite does not have enough bandwidth for the full HRV image, so a compromise is adopted whereby only half the scanned image width is sent down to the ground, but that half-width is moved during the scan to cover both Europe in the northern part and Africa in the southern part. During the afternoon, the southern part of the scan is moved to track the sun. This is likely to be the final format, and the MSG Data Manager correctly handles such split images. The image is transmitted in this format – it is not an error or defect. There is a 2MB animation from EUMETSAT showing this here.
