What Is Ozone Layer

The upper layer of the atmosphere encompassed by ozone is known as ozonosphere. The ozone layer is a protective layer, also called ozone umbrella. Ozone concentration differs by approximately 10 ppm in the stratosphere compared to 0.05 ppm in the troposphere. To the size of the continent, this hole reached by the year 1985. Factors Affecting 03 Layer Depletion - The root cause of 03 layer imbalance is that the existence of chlorine-containing gases. Due to the existence of UV light, these gases release chlorine atom, which leads to destruction and dissociates. It enhanced in the existence of polar stratospheric clouds, although the chlorine ion catalyzing depletion may take place in the phase.
During cold in winters, stratospheric clouds are formed. These clouds reside in vortex shaped at poles since the winters that are polar are without radiation for 3 months, they're cool and dark. Molecules are found in this PSC but are connected with a few elements such as shape and hydrogen HC1 and N03 to form C10N02. During spring when the clouds begin disappearing all these Cl compounds are dissociated and free radical of chlorine is discharged which attach on O3 layer to split it in 0molecule/atom. Hence clouds act as a reservoir for all these chlorine gases. The ozone hole is measured over a point on the surface that's usually expressed in Dobson unit, as the reduction in the entire column of ozone.
Effect of Ozone Depletion - Affects on Human Beings: UV radiation causes irritation and develops red patches on the skin.
The prolonged accumulative exposure to UV-B rays causes carcinoma, basal cell malignant neoplastic disease, epithelial cell malignant neoplastic disease, and skin cancer etc.
UV radiations cause blood vessels near this skin surface to take more blood causing suntan and skin aging. Chlorofluorocarbons are shown in black, additional ODSs from hydrochlorofluorocarbons are in gray. Note: HCFCs that have been utilized as CFC substitutes under this Protocol, lead to less ozone, destruction compared to CFCs. Combined effective abundances of ozone-depleting chlorine and bromine in this stratosphere.
The range reflects uncertainties because of this lag time between emission at this surface and this stratosphere, as well as several hypothetical ODS emission scenarios. Total global ozone change. Seasonal, quasi-biennial oscillation, volcanic and solar effects have been removed. The black line shows measurements. The grey area commonly reflects this evolution of ozone predicted by models that include this range of future potential climate conditions. Pre-1980 values, on this left of this vertical dashed line, are frequently utilized as a benchmark for ozone and UV recover. Estimated change in UV erythemal irradiance for the high sun.
