Before and After Satellite Images Show Storm Effects
NASA Earth Observatory released satellite images that show the power outages in the Washington-Baltimore metropolitan area that occurred as a result of a rare, fast-moving "derecho" thunderstorm system on Friday, June 29th.
These images were taken with the day/night band of S-NPP's Visible Infrared Imaging Radiometer Suite (VIIRS). The Suomi NPP satellite was launched from Vandenberg Air Force Base on October 28th, 2011 and is the result of a partnership between NASA, the National Oceanic and Atmospheric Administration, and the Department of Defense.
