Question

---------- gas protects us from the harmful ultraviolet rays of the sun ​

Answer 1

Answer:

Explanation:

Ozone layer

Ozone layer and ultra-violet radiation. The ozone layer protects us from potentially harmful ultraviolet (UV) radiation. CAMS monitors stratospheric ozone and provides UV forecasts based on this information. Ozone is a colourless and very reactive gas that can be found throughout all layers of our atmosphere.

Answer 2

Answer: hope this answer will help u

Explanation:

he ozone layer protects us from potentially harmful ultraviolet (UV) radiation. CAMS monitors stratospheric ozone and provides UV forecasts based on this information.

Ozone is a colourless and very reactive gas that can be found throughout all layers of our atmosphere. Most ozone (about 90%) is found in the stratosphere, which begins at about 10–16 kilometres above Earth’s surface and extends to an altitude of about 50 kilometres. Ozone in the stratosphere protects life on Earth from harmful ultraviolet (UV) radiation and is therefore often called 'good' ozone. This in contrast to ozone in the troposphere, the lowest layer of the atmosphere, where it is an air pollutant and can be harmful to humans, animals and vegetation.

ozone in the atmosphere

Over the last few decades, emissions of human-made chemicals have impacted the amount of ozone in the atmosphere. This is most obvious over the Antarctic, where the chemical destruction of ozone is known as the ‘ozone hole’, but these chemicals affect stratospheric ozone concentrations worldwide. On 1 January 1989, the Montreal Protocol on Substances that Deplete the Ozone Layer (a protocol to the Vienna Convention for the Protection of the Ozone Layer) entered into force as an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion. As a result of this first universally ratified treaty in United Nations history the ozone layer is slowly recovering. To ensure the treaty is successfully executed over this long time period, policy makers need information about the amounts of ozone and related chemical species in the stratosphere.

CAMS monitors the ozone layer on a daily basis showing, for instance, the extent and magnitude of the ozone hole each year as it develops and recovers. CAMS also provides a historical record from 2003 to the present based on its global reanalysis that combines observations with the CAMS global models describing the composition of the atmosphere.

In addition to this, on a daily basis, CAMS monitors and forecasts the amount of UV radiation reaching the surface of the Earth, taking into account the effect of ozone, clouds, and aerosol particles.
