A strong winter storm swept across Turkey in mid-January 2022, leaving
a blanket of snow behind. According to local news, thousands of people
were stranded on the Tarsus-Adana-Gaziantep Motorway, a highway in
southern Turkey, that was covered with snow and ice on January 18-19.
An article by Daily Sabah state that around 186 people in need of
medical care were evacuated to hospitals and that crews also
distributed food to some 7,000 people on the highway where the vehicles
could not move to low visibility and thick snow. Temperatures dropped
in Gaziantep, a city in the westernmost part of Turkey’s Southeastern
Anatolia region, to -3˚C (-26.6˚F) and snow piled 50 centimeters (19.7
inches deep).

The Moderate Resolution Imaging Spectroradiometer (MODIS) on board
NASA’s Terra satellite acquired a false-color image of the snowy scene
on January 20. This type of image uses infrared and visible light
(MODIS bands 7,2,1) to help differentiate between snow and cloud, both
which appear bright white in true-color images. In this type of image,
snow appears electric blue while cloud remains bright white, although
high, cold cloud that contains ice crystals may have a light wash of
blue. Vegetation looks green, open land appears tan, and water appears
black or inky-blue. On January 20, snow stretches across Turkey, with
the thickest snow blanketing the southeast section of the country.
