what is the relationship between solar radiation and stratospheric ozone?
445171
When the sky is clear, there is an inverse relationship between stratospheric ozone and solar UVR measured at the Earth's surface. That is,the lower the ozone levels, the higher the solar UVR. The level of UVR from the sun measured at the Earth's surface varies linearly with latitude.

Unlike stratospheric ozone, which forms naturally in the upper atmosphere and protects us from the sun's harmful ultraviolet rays, ground-level (or tropospheric) ozone is created through the interactions of man-made (and natural) emissions of volatile organic compounds and nitrogen oxides in the presence of heat and ...

Solar energy enters our atmosphere as shortwave radiation in the form of ultraviolet (UV) rays (the ones that give us sunburn) and visible light. The sun emits shortwave radiation because it is extremely hot and has a lot of energy to give off.

UV levels are higher closer to the equator. Closer to the equator the sun's rays have a shorter distance to travel through the atmosphere and therefore less of the harmful UV radiation can be absorbed.

It absorbs solar ultraviolet radiation, which heats the stratosphere. It also absorbs infrared radiation emitted by the Earth's surface, effectively trapping heat in the troposphere. Therefore, the climate impact of changes in ozone concentrations varies with the altitude at which these ozone changes occur.

The atmosphere acts as a gigantic filter, keeping out most ultraviolet radiation while letting in the sun's warming rays. Ultraviolet radiation is harmful to living things, and is what causes sunburns. Solar heat, on the other hand, is necessary for all life on Earth. Earth's atmosphere has a layered structure.

Ozone can be “good” or “bad” for health and the environment depending on where it's found in the atmosphere. Stratospheric ozone is “good” because it protects living things from ultraviolet radiation from the sun. ... Ozone occurs both in the Earth's upper atmosphere and at ground level.

The atmosphere, heated by the absorption of Earth radiation by these greenhouse gasses, in turn radiates heat back to the Earth's surface increasing the Earth's surface temperature. Transparency: The Earth's atmosphere is effectively transparent to solar radiation between .

Usually there is a fine balance between the build up and loss of ozone. However, any decrease in the amount of ozone in the ozone layer will increase the amount of UV radiation reaching the Earth's surface, and worsen the impacts due to UV exposure. ... Finally, UV rays can damage paint, clothing and other materials.

Photochemical smog is formed when sunlight interacts with certain chemicals in the atmosphere. Ozone is the main component in this type of air pollution. Ozone in the stratosphere protects us against harmful ultraviolet radiation, but on the ground, it is hazardous to human health.

The ozone layer is created when ultraviolet rays react with oxygen molecules (O2) to create ozone (O3) and atomic oxygen (O). This process is called the Chapman cycle. Step 1: An oxygen molecules is photolyzed by solar radiation, creating two oxygen radicals: hν+O2→2O.

The maximum intensity of the sun's output of radiation is in the visible light region. At the top of the atmosphere, approximately 7% of the radiation is in the ultraviolet, 41% in the visible, and 52% in the infrared.

Ultraviolet radiation (UV radiation) is energy created by the sun. ... The ozone layer is a section of the Earth's atmosphere that acts as a barrier between the Earth and UV radiation. The ozone layer protects the Earth from too much radiation by both absorbing and reflecting harmful UV rays.

For billions of years, our atmosphere has been: The stratospheric ozone layer—the part of the atmosphere that protects us from the sun's ultraviolet radiation—has deteriorated. 2. The increasing level of “greenhouse gases” in the atmosphere is raising Earth's temperature faster than at any time in the past.

Stratospheric ozone is important because it prevents most of the high-energy ultraviolet solar radiation from reaching the earth's surface. ... Without the protective ozone layer in the upper atmosphere life (as we know it) on earth would not be possible.

ULTRAVIOLET ASTRONOMY Since the Earth's atmosphere absorbs much of the high-energy ultraviolet radiation, scientists use data from satellites positioned above the atmosphere, in orbit around the Earth, to sense UV radiation coming from our Sun and other astronomical objects.

Ozone is technically a greenhouse gas, but ozone is helpful or harmful depending on where it is found in the earth's atmosphere. ... The protective benefit of stratospheric ozone outweighs its contribution to the greenhouse effect and to global warming.
