  2. NCC Imagery EDR Example SVDNB NCC The top image shows a DNB granule that crosses the day/night terminator. The lower image shows the associated NCC granule (with N/A fill values highlighted in blue). Neither image has been mapped. The goal of the NCC EDR is to reduce the dynamic range of DNB radiance values (which span 7 orders of magnitude between day and night) by converting it to a quantity with reduced dynamic range (i.e. reflectance) to create images with nearly constant contrast across scenes like this. Nighttime images of clouds should, in theory, appear similar to daytime images. This is a difficult problem, however…
