O3P
Description
The ozone profile is defined as the amount of ozone distribution per unit area per vertical altitude section of the atmosphere. Ozone is mainly produced in the stratosphere due to the sun's ultraviolet rays, showing a maximum ozone concentration in the 19-28 km layer and transported to the troposphere and extinct. Ozone is a gaseous substance with strong oxidizing power. In the troposphere, it is mainly produced by secondary photochemical reactions such as nitrogen oxides or volatile organic compounds such as exhaust gas, and has strong oxidizing power, causing damage to human body and crops(plants).
Applications
The amount of ozone in the troposphere can be identified because the ozone profile information is used to detect the amount of ozone at different vertical altitudes. Ozone in the troposphere is a major source of photochemical smog and a pollutant with strong oxidizing power, and is regulated as an air pollutant in the Air Environment Conservation Act. Therefore, it can be used for monitoring the air environment for public health.
The ozone profile information is calculated through inverse calculation from the observed radiation amount assuming the amount of vertical ozone. Since 90% of ozone is concentrated in the stratosphere and the ultraviolet wavelength band used for observation is sensitive in the stratosphere, the signal corresponding to the troposphere is relatively weak. Therefore, when interpreting the calculated ozone profile information, it should be taken into account that the amount of ozone at the altitude of the troposphere is relatively more uncertain than that of the stratosphere.
