This map illustrates satellite-detected areas of visible light at night in an area of Aleppo and Idlib Governorates as detected by VIIRS Day/Night band sensor on two different dates spanning the onset of violent conflict and current conditions. The red areas illustrate the areas which were lit at night during August 2012 and best indicate nighttime lights prior to widespread violent conflict. Conversely, the yellow areas illustrate lighted areas as seen in May 2014 after more than a year of heavy fighting in the area. Areas currently likely to be experiencing blackout conditions at the present time are therefore indicated in red. This includes large areas of the city of Aleppo as well as multiple outlying towns and villages. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.
