• CO2
  • ​Carbon dioxide is meteorologically a very important gas as it is transparent to the incoming solar radiation but opaque to the outgoing terrestrial radiation.
  • It absorbs a part of terrestrial radiation and reflects back some part of it towards the earth’s surface.
  • It is largely responsible for the greenhouse effect.
  • Its concentration is greater close to the earth’s surface as it is denser than air.
• SO2​
  • ​The most common pollutants that accelerated corrosion were sulfur dioxide, dust, and humidity.
• NO
  • NO and NO₂ (nitric oxide or nitrogen oxide and nitrogen dioxide) emissions cause global cooling through the formation of (OH) radicals that destroy methane molecules, countering the effect of GHGs.
• CO
  • Carbon monoxide is a short-lived greenhouse gas (it is less dense than air).
  • It has an indirect radiative forcing effect by elevating concentrations of methane and tropospheric ozone through chemical reactions with other atmospheric constituents (e.g., the hydroxyl radical, OH.) that would otherwise destroy them.
  • Through natural processes in the atmosphere, it is eventually oxidized to carbon dioxide.
  • Carbon monoxide poisoning causes a variety of symptoms as it deprives the body and brain of oxygen.
    • A headache and vision problems, such as blurred vision, are common signs of carbon monoxide poisoning.
