    The sensitivity of the ozone is rather robust in the upper mesosphere and lower stratosphere. In the mesosphere its magnitude gradually rises from % at 65 km to –1% at 75 km. In the lower stratosphere, the ozone sensitivity is within –%. In the middle and upper stratosphere, the ozone sensitivity is not by: About 90% of the ozone in the Earth's atmosphere is found in the region called the is the atmospheric layer between 16 and 48 kilometers (10 and 30 miles) above the Earth's surface. Ozone forms a kind of layer in the stratosphere, where it is more concentrated than anywhere else.. Ozone and oxygen molecules in the stratosphere absorb ultraviolet light from the Sun, providing.

(We have checked this procedure by repeating the 'satellite observation' and mapping calculations with a special data set of shorter duration in which the 01 values were saved every 2 h. The differences between the two were seen to be negligible for Cited by: 2.

Ozone is a gas made up of three oxygen atoms (O 3). It occurs naturally in small 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 kilometers altitude.

As this ozone climatology is neither dependent on a priori data nor 49 photochemical modeling, it provides independent information and insight that can supplement 50 satellite data and model simulations of stratospheric ozone.

The concept mentioned above implies that the time scale of ozone might be rather short in the lower stratosphere.

The order of the half restoration time was estimated to be 10 to 10 2 days in the lower stratosphere. Thus the estimated time scale of ozone must be somewhat longer than that of the temperature in the lower stratosphere, of which Author: Yoshiro Sekiguchi.

Examined are temperature and ozone variations in the Northern Hemisphere stratosphere during the period –77, as estimated from radiosondes rocketsondes, ozonesondes, and Umkehr measurements. The temperature variation in the low tropical stratosphere is a combination of the variation associated with the quasi-biennial oscillation, and a variation nearly out of phase with the Cited by: 6.In the stratosphere, the Brewer-Dobson circulation carries air from the equator to the poles.

Poleward of about 30°N and 30°S, the circulation becomes downward as well as poleward. This poleward and downward circulation tends to increase ozone concentrations in the lower stratosphere of the middle and high (i.e. extratropical) Size: KB.Bad ozone also absorbs solar ultraviolet light, but it is down near Earth's surface where we can breathe it.

For UV protection, we are interested in the total number of ozone molecules between us and the Sun. 90% of ozone molecules are in the stratosphere and 10% are in the troposphere - some down near Earth's surface where we can breathe them.
