   The stunning colors of New Zealand’s South Island shone on March 18,
   2021, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on
   board NASA’s Aqua satellite acquired a true-color image of a rare
   cloud-free late summer day.

   The Southern Alps stretch down the length of South Island, capped with
   snow and glaciers year-round. On this day, clouds also covered much of
   the western slopes and the western coast—not unusual at any time of the
   year as the West Coast of South Island is the wettest region anywhere
   in New Zealand. Thanks to the tall mountains and the resultant rain
   shadow, the area just east of the mountains is one of the driest areas
   in New Zealand.

   While most of South Island experiences copious sunshine, capturing
   satellite images of the island can be difficult due to frequent and
   shifting cloud patterns brought by the island’s position in the
   “Roaring 40s”. This is a wide belt of gale-force westerly winds that
   circle the Southern Hemisphere, bringing storms and copious clouds.
   Clouds are so frequent—and so appreciated—that they are frequently used
   in common names. For example, the highest peak in the Southern Alps
   (and in New Zealand) is Aoraki/Mount Cook at 3,754 meters (12,316 ft).
   The native name is said to translate to “The Cloud Piercer”, a nod to
   the dramatic clouds that so frequently sit around the mountaintop.
