View the latest status of the ozone layer over the antarctic, with a focus on the ozone hole satellite instruments monitor the ozone layer, and we use their data to create the images that depict the amount of ozone. Research indicates that depletion of the good ozone layer is being reduced worldwide thinning of the protective ozone layer can be observed using satellite measurements, particularly over the polar regions how.
[toc] what is the ozone layer ozone is a naturally occurring molecule containing three atoms of oxygen ozone molecules form a gaseous layer mostly in the upper atmosphere ozone layer depletion cfcs (chlorofluorocarbons), halons.

Hello anusha , credible scientific studies have substantiated that the cause of ozone layer depletion is human activity, specifically, human-made chemicals that contain chlorine or bromine these chemicals are widely known as ods, an acronym for o. Define ozone layer: indicate that depletion of the protective ozone layer over antarctica was about 20 percent lower during the 2016 antarctic winter a layer of ozone in the upper atmosphere that prevents dangerous radiation from the sun from reaching the surface of the earth.
The dangers of the depletion of the ozone layer
The ozone (o3) filters about 99% of ultraviolet radiation reaching us from the sun and necessary for the life on the earth. Learn about the human health and environmental effects of ozone layer depletion.
- The ozone layer or ozone shield is a region of earth's stratosphere that absorbs unabsorbed and dangerous ultraviolet radiation is able to reach the earth's scientists announced that the global depletion of the ozone layer may be slowing down because of the international regulation.
- It's pretty confusing when we hear about the dangers of ozone depletion one day and the need to reduce ozone the next ozone gas is extremely helpful -- but only when it's miles away from us in the ozone layer.
