The Day/Night band on Suomi/NPP produces Night-Time visible imagery using illumination from natural (the moon, forest fires) and man-made sources (city lights, gas flares). Interpretation of the imagery should be done, therefore, with a knowledge of the Lunar phase. In the example above, note the dimming of the clouds over... Read More
On 05 December 2012 NASA and the NOAA National Geophysical Data Center (NGDC) jointly released a “Black Marble” global composite of night-time Suomi NPP VIIRS 0.7 µm Day/Night Band imagery (collected from multiple cloud-free satellite overpasses in April and October 2012) — the image above shows this dataset visualized using...

AWIPS images of Suomi NPP VIIRS 0.7 µm Day/Night Band and 11.45 µm IR channel data (above) showed a thunderstorm complex that stretched from northern Missouri to southern Illinois at 08:23 UTC (3:23 AM local time) on 25 September 2012. The IR image revealed a number of cold overshooting tops... Read More
The image above from the SSEC Web Map Service (WMS) shows visible imagery of Tropical Storm Chris over the central Atlantic on June 20th, just south of the north wall of the Gulf Stream. Sea-surface temperatures are indicated by the color shading. The projected path of the storm, and the cone of uncertainty... Read More
