Tropospheric ozone
- Scientists have found relatively low concentration of Ozone over Guwahati near surface ozone in the Brahmaputra River Valley (BRV) compared to the other urban locations in India.
- Tropospheric, or ground-level ozone, is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC).
- It usually increases when pollutants emitted by cars, power plants and other sources chemically react in the presence of sunlight, impacting human health.
