Tropical Storm Isaac by Night

    NASA image acquired August 28, 2012

    Early on August 28, 2012, the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi-NPP satellite captured this nighttime view of Tropical Storm Isaac and the cities near the Gulf Coast of the United States. The image was acquired just after local midnight by the VIIRS “day-night band,” which detects light in a range of wavelengths from green to near-infrared and uses light intensification to enable the detection of dim signals. In this case, the clouds of Isaac were lit by moonlight.

      what does "and uses light intensification" mean? just turns up the gain digitally? uses special circuits? a photomultiplier tube?

      Why can't NOAA have a light intensifying satellite?

      It means they reversed the polarity...
