Analysis with VIIRS Data Acquired 25 April 2015 & 20 March 2015

This map illustrates satellite-detected areas of visible light at night in western Yemen. The red areas illustrate the areas which were lit at night during 25 April 2015 and best indicate nighttime lights during widespread violent conflict. Conversely, the yellow areas illustrate lighted areas as seen in 20 March 2015, prior to conflict. Areas currently likely to be experiencing electrical blackout conditions at the present time are therefore indicated in yellow. This includes large areas in Sana'a and Aden and other cities like Sadah, Ibb and Damar. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.
