Ozone layer thickness is expressed in Dobson units (DU). 1 DU is the thickness of pure ozone gas at standard conditions of temperature and pressure.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).The Dobson unit is defined as the thickness (in units of 10 μm) of that layer of pure gas which would be formed by the total column amount at standard conditions for temperature and pressure . a researcher at the University of Oxford who in the 1920s built the first instrument to measure total ozone from the ground, .
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 squareThe correct option is A Dobson Unit. The thickness of the ozone layer in a column of air from the ground to the top of the atmosphere is measured in terms of Dobson Units (DU).The thickness of the ozone layer is not measured in traditional distance units because the ozone in the atmosphere is not uniformly distributed and it fluctuates with time and location. Instead, the amount of ozone in the atmosphere is often expressed in Dobson Units (DU), which measure the number of ozone molecules in a column of air. .
Q1 What is ozone, how is it formed, and where is it in the
View the latest status of the ozone layer over the Antarctic, with a focus on the ozone hole. . The Dobson Unit (DU) is the unit of measure for total ozone. If you were to take all the ozone in a column of air stretching from the surface of the earth to space, and bring all that ozone to standard temperature (0 °Celsius) and pressure (1013. .
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 .The correct option is B Dobson units. The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson. Its properties were explored in detail by the British meteorologist G. M. B. Dobson, who developed a simple spectrophotometer (the Dobson Miter) that could be used to measure stratospheric ozone from the ground. Total ozone measured by ground-based Dobsons and satellite-based instruments, from contour plots of total ozone (Dobson unit, Du) by latitude and month. Left . In Fig. 3.6 total ozone layer thickness from satellite data is plotted as a function of latitude and time, from 1995 to 2008. The low values over low latitudes, high values over North . 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.
“ozone layer” (see Figure Q1-2). The ozone layer extends over the entire globe with some variation in altitude and thickness. Most of the remaining ozone (about 10%) is found in the tropo-sphere, which is the lowest region of the atmosphere, between Earth’s surface and the stratosphere.

Editor’s note: This article has been updated to clarify the ranking of the 2023 ozone hole. It is the 12th largest single-day hole on record, and the 16th largest when averaged from Sept. 7 to Oct. 13. The 2023 Antarctic ozone hole reached its maximum size on Sept. 21, according to annual satellite and balloon-based measurements made by NASA and NOAA. 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 .
Over the Earth’s surface, the ozone layer’s average thickness is about 300 Dobson Units or a layer that is 3 millimeters thick. Seen from space, the edge of the Earth is blurred by the pale blue atmosphere. . until it gradually merges with vacuum. Total ozone is measured through the entire atmospheric column, from the surface to the edge . What is the ozone layer? The ozone layer ozone layerThe region of the stratosphere containing the bulk of atmospheric ozone. The ozone layer lies approximately 15-40 kilometers (10-25 miles) above the Earth's surface, in the stratosphere.
These instruments measure how thick the ozone layer would be if compressed in the Earth’s atmosphere (at sea level and at 0°C), where one Dobson Unit (DU) is defined to be 0.01 mm thickness at standard temperature and pressure.
