LARGEST KNOWN HOLE DETECTED ON ARCTIC SIDE OF OZONE LAYER

A large hole has been detected in the Arctic portion of the ozone layer.

This hole in the ozone layer is described as the largest hole ever detected in the region.

Diego Loyola of the German Space Center says a huge hole has been detected in the Arctic section of the ozone layer. Loyola said the hole in the ozone layer reached an area of 1,600,000 square kilometers after it was detected in February.

Measurements made in the region after the hole in the ozone layer was detected indicate that ozone levels in the region have dropped. Scientists say it is unusual for the ozone layer to be drilled in the Arctic for several reasons. In Antarctica, where the temperature has dropped to very low levels, holes in the ozone layer have been reported every year. But no ozone layer holes had been detected in the Arctic since 2011.

In Antarctica, ozone layer holes have been detected since 1985

There are holes in the ozone layer because of man-made chemicals. The first ozone layer hole in Antarctica was detected in 1985. Since that year, new ozone layer holes have been detected in the region every year.

One of those responsible for drilling the ozone layer is chlorofluorocarbonate (CFCs). Until it was banned in 1996, CFCs were in use in many areas, accumulating in the ozone layer, causing them to be drilled.

Antarctica's extreme cold, the folds in stratospheric clouds that facilitate the reaction of CFCs with the ozone layer, enable the formation of polar vortexes. This is why new ozone layer holes are detected every year in Antarctica.

Vincent-Henri Peuch, director of the European Union's Copernicus Atmosphere Monitoring Service, said the high-altitude mountainous terrain in the Arctic breaks the strength of the polar vortex, so ozone layer holes are rarely seen in the Arctic region. Although rare, ozone layer holes have also been seen in the Arctic region, Peuch said, but it is not clear exactly why the new ozone layer hole of record size was formed.

What does the ozone layer hole in the Arctic mean?

February and March, Vincent-Henri Peuch explained, because of the hole, ozone levels in the region fell rapidly. The decrease in ozone levels in the ozone layer, which protects the earth from ultraviolet rays, means that more UV radiation will be seen during this period.

After the formation of holes in the ozone layer, the UV index in the region reached 5. This UV index for the Arctic region is much higher than it should be. But for many countries, including the United States, it is normal for this UV index to be at a level of 5 or 6.

Vincent-Henri Peuch said the ozone layer hole in the Arctic region does not pose a problem for humans, despite its unconventional dimensions for the region. The effects of the hole in the ozone layer will be quite low, as increased UV radiation affects the region of Greenland, where the population is sparse and radiation exposure is low.
