When we think of the ozone layer, we usually imagine a protective shield high above Earth, stretching across the atmosphere and absorbing harmful ultraviolet rays from the Sun. Normally, the ozone layer peaks at altitudes of 25–30 km. But during a nationwide campaign called NetRAD-ASMA, scientists found an unusually thick ozone layer between 21 and 23 km above the Bay of Bengal. The 2021 Antarctic ozone hole reached its maximum areaTo protect life on Earth, we have the ozone layer, which protects us from ultraviolet rays. Ozone at lower latitudes is not recovering, despite Antarctic ozone hole healingThe pocket of ozone over the Bay of Bengal is no mere curiosity.
