Early snowfall visible on VIIRS DNB Reflectance

Here is a posted application of the VIIRS Day-Night Band by the NWS Forecast Office in Great Falls. It was posted on their local blog.


Clear skies and a bright moon in the early morning hours on September 12th 2014 allowed for good view of the extent of recent snowfall on the VIIRS Day-Night Band Reflectance imagery. At 1km resolution it’s about as detailed as a GOES visible image during daylight.
