Ozone Mini Holes In The Arctic And Strong Ozone Concentrations In The Arctic

Ozone mini holes in the Arctic and a team of scientists from the German Aerospace Center (DLR), using data from the tropomy team from ESA’s Precurs Copernicus Sentinel-5 satellite, also known as Sentinel-5P. They demonstrated strong ozone concentrations in the Arctic. It looks scattering. DLR researchers noticed an unusual ozone mini holes over the Arctic.

Ozone mini holes

The ozone layer is a protective layer of natural gas in the stratosphere that protects life from the sun’s harmful ultraviolet radiation. Which is associated with skin cancer and cataracts, as well as other environmental problems. The most commonly known “ozone hole” is the hole in Antarctica, which occurs every year during the fall.

Small ozone holes are occasionally seen at the North Pole, but this year the decline in the Arctic is much greater than in previous years. The ozone hole we see over the Arctic this year has a maximum expansion of 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 about 20 to 25 million km2 with a normal duration of about 3 to 4 months. Although both poles experience ozone loss during winter, ozone depletion in the Arctic is much lower than in Antarctica.

polar vortex

The ozone hole is governed by extremely cold temperatures (below 80 ° C), sunlight, wind fields. Arctic temperatures in Antarctica are generally not that low. However, this year strong winds moving around the North Pole caused an eruption of cold air, called a “polar vortex,” a stratospheric wind tornado.

At the end of the polar winter, the first sun at the North Pole lacked this unusually strong ozone, 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.

Ozone mini holes

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.

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.

ESA publication

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.

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. Scientists observe unusual ozone hole in the Arctic

German Aerospace Center

Scientists at the German Aerospace Center (DLR) have observed an area in the atmosphere with decreasing ozone levels over the Arctic. This depletion of the ozone layer has previously been observed at the North Pole.

But this time the depletion is unusually strong. The European Space Agency explained in its article: “Unusual atmospheric conditions, including the decrease in temperature in the stratosphere, have caused ozone levels to drop, creating a ‘mini-hole’ in the ozone layer.”

Scientists believe that the reason behind this mini ozone hole is likely due to extreme weather in the Arctic this year. Whereas the ozone layer is considered as the “level of the ozone hole”. The ozone layer is a protective layer that protects the Earth from ultraviolet radiation from the sun.

DLR scientists

Every winter the temperature drops and the ozone layer ends at the north and south poles. But the erosion of the ozone layer is much greater near Antarctica than in the Arctic because the temperature in the south is much lower than in the north.

This great depletion of the ozone layer leads to the formation of an ozone hole seasonally in Antarctica. Now, while observing the ozone layer with the help of a tropomy kit on the Copernicus Sentinel-5P satellite in the Arctic, DLR scientists have observed an unusually large area of ozone depletion.

Diego Loyola of DLR stated in a statement: The ozone hole that we see over the Arctic this year has a maximum expansion of less than 1 million square kilometers. It is smaller than the Antarctic Hole. Which can reach a size of approximately 20 to 25 million square kilometers with a normal duration of approximately 3 to 4 months.
