      a fellow breezy weather user!
      you can tap on it to read more about it.

      Ground-level ozone (O3) is a major component of smog. Although the same molecule, ground-level ozone can be harmful to human health, unlike stratospheric ozone that protects the earth from excess UV radiation. It is formed from photochemical reactions with pollutants such volatile organic compounds, carbon monoxide and nitrogen oxides (NO,) emitted from vehicles, and industry. Due to the photochemical nature, the highest levels of ozone are seen during periods of sunny weather. Exposure to excessive ozone can cause problems breathing, trigger asthma, reduce lung function and lead to lung disease.

      Ah apparently, it is more common to occur naturally in the countyside because the NOx from fossil fuels will react with the ozon to create NO² and O².
