This composite image of the world, called the “Black Marble,” was taken with the day-night band of NASA’s Visible Infrared Imaging Radiometer Suite (VIIRS). The day-night band sensor in the instrument was designed and developed by SRI using the latest extended dynamic range charge-coupled device (CCD) technology that can capture the finest details, even in low-light conditions.
Stunning images such as this one allow us to study in detail the impact of global climate change. Atmospheric scientists can use this new capability to observe and catalog changes that were once lost to darkness, such as weather patterns and clouds at night. The technology can help scientists to observe active wildfires, vegetation and ocean color changes.
