Researchers at the South Pole saw the last sunset on March 20, and will see sunrise only after 6 months.

March 20 marked the start of the austral autumn on March 20, 2016 where researchers in the Northern Hemisphere saw the Sun set for the last time before a really long night. Researchers at NOAA's South Pole Atmospheric Baseline Observatory marked the start of the austral autumn, the last time they see the sun for six months.

The observatory is part of the US Amundsen-Scott South Pole Station. Hardly a handful of people visit the place in summer and in winter, it’s so cold that even aircrafts can’t fly and scientists are marooned until late October. 

 

"It’s the coldest, driest, flattest place you can imagine," said NOAA Corps LT Jesse Milton.

The Atmospheric Research Observatory is the third-generation “clean air” facility that is located at the South Pole. It maintains one of the longest atmospheric carbon dioxide [greenhouse gas] record on earth.

Continuous long-term atmospheric records show how factories, households and cars thousands of miles away are changing the chemistry and composition of “cleanest air on earth.”

Ozone measurements have been instrumental for researchers studying the annual South Pole “Ozone Hole” offsite link.  Although the 9,305-foot altitude and temperatures dipping below -100°F make this one of the most inhospitable research sites on Earth, there are benefits.

 

The vast, flat polar plateau offers remarkable and unobscured views of the southern constellations, streaking satellites, and the fluttering, evanescent, Aurora Australis … from a vantage that few other humans have ever seen.
