Sun Sets at South Pole, Ushering in Six Months of Darkness

Apr 4, 2025 | Government, White House

On March 20, 2025, researchers at NOAA’s South Pole Atmospheric Baseline Observatory witnessed the sun dip below the horizon, initiating a six-month period of darkness. This annual sunset signifies the transition into austral autumn for the Southern Hemisphere. During this extended night, NOAA scientists continue their critical work, which includes:

  • Monitoring greenhouse gases to track climate change indicators.
  • Observing air quality to assess atmospheric conditions.
  • Tracking the Antarctic ozone hole during its peak formation months.

Despite the harsh conditions, the observatory’s location offers unparalleled opportunities for these essential scientific endeavors.
