Abstract:
Most of the earth's lower atmosphere is where the ozone layer is found. Between 97 and 99 percent of the harmful UV light that the sun generates which can endanger the life on Earth can be absorbed by it. Without the ozone layer may have weakened immune systems and millions of people would get skin diseases. Chlorofluorocarbons, methyl bromide, carbon tetrachloride, and hydro chlorofluorocarbons are the primary reasons behind the ozone hole. When bromine and chlorine atoms from the atmosphere come into attract with molecules of ozone then molecules of ozone's are destroyed in this process100, 000 ozone molecules can be destroyed by a single chlorine molecule. It is also destroyed faster than it is created. Bromine and Chlorine are released by some chemical when it is exposed to strong UV radiation, which contributes to the ozone layer's depletion. Chemicals that destroy the ozone layer include carbon tetrachloride, hydro chlorofluorocarbons, methyl chloroform, and chlorofluorocarbons. Methyl bromide, Halons and hydro bromofluoro carbons are ozone-depleting substances that also contain bromine. Chlorofluorocarbons are the material that destroys the ozone layer most frequently. The 2019 ozone hole was very small and transient due to unique meteorological circumstances. When considered collectively, ozone depletion mitigation is still in a very precarious state, and scientific data indicates that additional action is still needed to relieve pressure on the ozone layer brought on by ozone-depleting compounds. In comparison to the one from 2021 (24.8 million km2), On September 26, the Southern Hemisphere's ozone hole reached its largest size of 24.5 million km2. Copernicus Atmosphere Monitoring Service researchers claim that the ozone hole in 2022 has a similar size and durability as those in 2021 and 2020 because of those years' powerful and persistent polar vortices. Additionally, it was bigger in 2022 than it had been on average during the previous five and ten years (21.3 and 21.9 million km2, respectively). When contrast to the Southern Hemisphere, ozone depletion is often much more constrained in the Northern Hemisphere. However, ozone-stoned observations in the spring of 2020 in the Arctic showed ozone depletion that was brought on by abnormally strong, persistently cold temperatures in the stratosphere.
