Ozone layer
The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. It contains a high concentration of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer contains less than 10 parts per million of ozone, while the average ozone concentration in Earth's atmospher.

Solution for Thickness of the ozone layer The thickness of the ozone layer can be estimated using the formula In I, - In I = kx sec 0, where Io is the intensity . Io/I is measured as 1.72 and 0 = 12°. Approximate the thickness of the ozone layer to the nearest 0.01 centimeter.
Ozone is a gas made up of three oxygen atoms (O 3). It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere). Ozone protects life on Earth from the Sun’s ultraviolet (UV) radiation. . Ninety percent of the ozone in the atmosphere sits in the stratosphere, the layer of atmosphere between about 10 and 50 .also used routinely on board research aircraft to measure the distribution of ozone in the troposphere and lower stratosphere. High-altitude research aircraft can reach the ozone layer at most locations over the globe and can reach farthest into the layer at high latitudes in polar regions. Ozone measurements are also being made on some com . Ozone layer, region of the upper atmosphere, between roughly 15 and 35 km (9 and 22 miles) above Earth’s surface, containing relatively high concentrations of ozone molecules. Approximately 90 percent of the atmosphere’s ozone occurs from 10–18 km (6–11 miles) to about 50 km (about 30 miles) above Earth’s surface.
What is the measure for ozone layer - Ozone is measured as Dobson units. And a Dobson unit of gas is equal to a layer of gas, with a thickness of one-hundredth of a millimeter at the surface of the Earth. The ozone in the atmosphere is measured by about 300 Dobsons.Ozone is also known as a trace gas, meaning there are very few amounts i
The hole in the ozone layer — the portion of the stratosphere that protects our planet from the sun’s ultraviolet rays — is continuing to decrease. The hole over Antarctica had an average area of 8.91 million square miles (23.2 million square kilometers). That measurement is slightly smaller than the extent of 8.99 million square A thinning ozone layer means less protection from UV rays, which can cause sunburns, cataracts, and skin cancer in humans. . At NOAA’s South Pole Baseline Atmospheric Observatory, scientists measure the layer’s thickness by releasing weather balloons carrying ozonesondes and by making ground-based measurements with a Dobson spectrophotometer.The ozone layer is present in the stratosphere at a height of 16km to 25km. Ozone thickness is measured by Dobson units(D.U.) Ozonosphere works as a shield against UV radiation. Depletion in the concentration of the ozone layer called the ozone hole was first discovered by the Nimbus-7 satellite (1985).
