VIIRS Near-Constant Contrast DNB Image - 6 September 2017, 05:24 Z (9:24 am EST)

Near-Constant Contrast (NCC) satellite image of Hurricane Irma at 0524Z, 6 September 2017 as it approaches Puerto Rico. The NCC is a derived product of the Day/Night Band sensor that utilizes a sun/moon reflectance model that illuminates atmospheric features, senses reflected and emitted light sources, and assists with cloud monitoring during the nighttime. In the image, notice the island of Barbuda is located in the eye-wall of the hurricane. In the top- right corner of the image, the moon percent visibility and moon elevation angle are provided. A full moon present and a positive moon elevation angle imply that the moon was above the horizon, and provided adequate reflected moonlight of the ambient atmospheric features.
