9. Over land, Original Over land, De-striped Over water, Original Over water, De-striped Example of striping correction applied to Sounder band-7. Reduced striping (left to right) is seen for both water (top) and land (bottom) areas in enhanced images from. Striping however appears to have increased over the coldest cloud tops (top left to right).
