The scientists of USA Develop new method to assess ozone layer recovery

Scientists have develop a new method for assessing the impacts of Ozone destroying substances that threaten the recovery of the ozone layer

The Montreal protocol is successfully protecting the ozone layer but the recovery of ozone layer is slower than expected

The Integrated Ozone depletion (IOD) metric provides a useful tool for scientist 

The IOD has been designed to provide a straightforward way to measure the effects of unregulated emissions of substances that deplete the ozone layer

the IOD represents a simple means of calculating the impact of any given emission scenario on ozone recovery.

the stratosphere region of atmosphere is  acts as an important protection barrier against most of the sun’s harmful ultraviolet rays.

Ozone-depleting gases such as chlorofluorocarbons, better known as CFCs, have been phased out under the Montreal Protocol
