      By mid-February 2023, a large swath of snow covered the highlands south   
      of the Black Sea, stretching from the Anatolian Peninsula and across   
      the Caucasus and southward over the Zagros Mountains, thanks to several   
      January and February snowstorms.   
      
      The Moderate Resolution Imaging Spectroradiometer (MODIS) on board   
      NASA’s Aqua satellite acquired a false-color image of the widespread   
      winter scene on February 14. In this type of image snow looks electric   
      blue, vegetation bright green, open land is tan and water varies with   
      depth, from light blue to dark inky blue. Cloud typically looks white,   
      but high cloud that carries ice crystals may be tinted with light   
      electric blue.   
      
      Snow covers seven countries in this image. Beginning in the east, at   
      the shores of the Caspian Sea, and moving westward they are Azerbaijan   
      (north) and Iran (south), Georgia (touches the Black Sea), Armenia,   
      Iraq, Turkey (south of the Black Sea), and Syria. The countries can   
      also be located by the prominent lakes and reservoirs. In the   
      northeast, snow surrounds the dark waters of Lake Sevan, Armenia. Lake   
      Van, Turkey sits to the west and slightly south of Lake Sevan. The   
      snake-like lakes surrounded by snow west of Lake Van are reservoirs on   
      Turkey’s portion of the Euphrates River, including the large Karakaya   
      Dam Reservoir. As the Euphrates flows southward, it expands into   
      another reservoir, Lake Assad, which is Syria’s largest lake. Moving   
      south and east, a tear-drop-shaped lake, Lake Tharthar, sits in Iraq.   
      The lake with the most unusual appearance is Lake Urmia, Iran. The rich   
      blue-toned waters of this saline lake are surrounded by a ring of   
      bright electric blue. While it looks much like snow, the color ringing   
      Urmia more likely comes from the highly-reflective mineral crust that   
      covers the lake edge.
