The researchers detect ozone mini-holes in the Arctic. A team of scientists from the German Aerospace Center (DLR), using data from the tropomy team on ESA’s Precursor Copernicus Sentinel-5 satellite (also known as Sentinel-5P), demonstrated strong ozone concentrations over the Arctic.
Scarcity is observed. DLR researchers noticed an unusual mini ozone hole over the Arctic. The ozone layer is a protective, natural gas layer in the stratosphere that protects life from harmful ultraviolet radiation from the sun, which is associated with skin cancer and cataracts, as well as other environmental problems.
The most commonly referred to “ozone hole” is the hole in Antarctica, which occurs during the fall of each year. Small ozone holes are sometimes seen at the North Pole, but the decline in the Arctic this year is much greater than in previous years.
The maximum expansion of the ozone hole we see over the Arctic this year is less than 1 million km2, a DLR researcher Dr. Diego Loyola said. It is smaller than the Antarctic hole, which can reach a size of approximately 20 to 25 million km2 with a normal duration of approximately 3 to 4 months.
Although both poles experience ozone loss during the winter, ozone depletion in the Arctic is much less than in Antarctica. The ozone hole is governed by extremely cold temperatures (below 80 ° C), sunlight, wind fields, and substances such as chlorofluorocarbons. Arctic temperatures in Antarctica are generally not that low.
However, the strong winds that blew around the North Pole this year caused a blast of cold air known as the “polar vortex,” a whirlwind of stratospheric winds. At the end of the polar winter, the first sunlight at the North Pole led to this unusually strong ozone depletion, creating holes.
However, its size is still small, which can generally be seen in the southern hemisphere. “Since March 14, the ozone column over the Arctic has decreased, which is generally considered the level of the ozone hole, which is less than 220 Dobson units,” said Dr. Loyola. We expect the hole to close again in mid-April 2020.
“Total ozone measurements of tropism have been expanding Europe’s capacity for continuous global monitoring of ozone from space since 1995,” ESA Sentinel-5P mission manager Dr. Claus Zehner said. Scientists found an abnormal ozone hole in the Arctic – what caused it?
This ‘small hole’ in the ozone layer is believed to have been caused by unusual atmospheric conditions, including a drop in temperature in the stratosphere. Scientists noticed an unusual hole in the ozone layer over the Arctic. Scientists have seen a drastic decrease in ozone concentrations in the Arctic.
This ‘small hole’ in the ozone layer is believed to have been caused by unusual atmospheric conditions, including a drop in temperature in the stratosphere. The ozone layer is a protective layer of gas in the stratosphere that protects Earth from harmful ultraviolet radiation from the sun that could otherwise cause skin cancer and cataracts, among other environmental problems.
According to a press release shared by the European Space Agency (ESA), scientists from the German Aerospace Center (DLR) reported data from the Copernicus Sentinel-5P satellite to note an unusually sharp decline in ozone in the northern polar regions. What caused this unusual ozone hole over the Arctic.
According to ESA, substances such as cold temperatures (below -80 ° C), sunlight, wind fields, and chlorofluorocarbons (CFCs) are responsible for the ozone layer. Although the planet’s north and south poles experience ozone loss during the winter, ozone erosion in the Arctic is much less than in Antarctica. Although arctic temperatures in Antarctica have not dropped as low as this year.
The powerful winds that blow around the North Pole this year are known as polar vortices, a spiral of stratospheric winds. At the end of the polar winter, the first sunlight at the North Pole led to this unusually strong ozone depletion, creating holes. However, its size is still small, which can generally be seen in the southern hemisphere.
The report noted. Arctic ozone hole boundary: ESA Copernicus Sentinel-5P mission manager Klaus Zehner said: Tropomy’s total ozone measurements have expanded Europe’s ability to continuously monitor global ozone from space since 1995.
Right now, we have an ozone I haven’t seen this size hole over the Arctic Diego Loyola of the German Aerospace Center said the Arctic hole is expected to close again in mid-April 2020. Ozone recovery: Based on the scientific assessment of 2018 ozone depletion data, the ozone layer in parts of the stratosphere has recovered since 2000 at a rate of 1-3 percent per decade.
At these projected rates, the Ozone Report for the Northern Hemisphere and Mid Latitude indicated that it was forecast to recover around 2030, the Southern Hemisphere around 2050, and the polar regions by 2060. At this time, we have not seen the formation of an ozone hole of this size over the Arctic.
An unusually large hole has been cut in the Arctic ozone layer. In the past month, a new hole has begun to form in the ozone layer over the Arctic. The ozone layer at the North Pole has been eroded many times in the past. But according to a press release from the European Space Agency.
This time the extreme weather and atmospheric conditions have caused a much larger decline than normal. While ESA scientists expect it to close later this month. It is a disturbing update on the planet’s environmental health.
This year’s Arctic ozone hole is larger than normal due to unusually cold temperatures in the stratosphere, helping to get trapped in a vortex of icy air called polar vortices in the area that had spread more ozone than normal. in that area.
However, even this unusually large hole in the ozone layer is much smaller than the best-known hole in Antarctica according to the ESA publication. It can be up to 25 million square kilometers, although it has recently become smaller, and the new Arctic hole is less than 1 million square kilometers.
It is unclear what to expect in the coming years. While the larger than average ozone hole was caused by extreme weather, which has been linked to climate change, Arctic ozone depletion will soon be declared to continue to worsen if climate change continues unchecked.
But we know that ozone depletion can lead to extreme weather worldwide, which means that ozone depletion may have far-reaching effects in the future.
