BLACKOUT IN SYRIA

Payne Institute Earth Observation Group reports on the Blackout in Syria. At night, the NASA/NOAA Visible Infrared Imaging Radiometer Suite (VIIRS) collects visible wavelength low-light imaging data in a Day / Night Band (DNB).  The DNB is designed for cloud imaging using moonlight (instead of sunlight) as the illumination source.  The DNB also detects electric lighting and features like gas flares.  The Earth Observation Group (EOG) generates monthly global cloud-free averages of the DNB radiance.
