ózontartalom

ózontartalom refers to the concentration of ozone (O3) in a given medium, typically the Earth's atmosphere or a specific air sample. Ozone is a molecule composed of three oxygen atoms. In the stratosphere, ozone plays a crucial role in absorbing ultraviolet (UV) radiation from the sun, protecting life on Earth from its harmful effects. The concentration of ozone in this region is referred to as stratospheric ozone content.

In the troposphere, the lowest layer of the atmosphere, ozone is considered a pollutant. Tropospheric ozone content is influenced by various factors, including emissions of precursor pollutants like nitrogen oxides (NOx) and volatile organic compounds (VOCs), as well as sunlight. High levels of tropospheric ozone can be detrimental to human health, causing respiratory problems, and can also damage vegetation and ecosystems.

Measurements of ozontartalom are conducted using various instruments, including ground-based ozone sondes, satellite-based sensors, and in-situ air quality monitors. These measurements are essential for monitoring ozone depletion in the stratosphere, understanding the formation and transport of ozone in the troposphere, and assessing compliance with air quality standards. Changes in ozontartalom can have significant environmental and health implications, making its study and monitoring vital for environmental science and public health.
