It presents air pollution data at the county-level for two pollutants, deadly fine particulate matter (PM 2.5 ) and ground-level ozone. is emitted directly from the tailpipes of gasoline and diesel vehicles, while ozone and even more PM 2.5 and ozone pollution 1. Internal combustion vehicles are largely to blame, since PM 2.5

The fact that there is a natural greenhouse effect (that the atmosphere restricts the passage of infra-red (IR) radiation from the Earth’s surface to space) is easily deducible from; i) the mean temperature of the surface (around 15ºC) and, ii) knowing that the planet is normally close to radiative equilibrium. in IPCC TAR).

They do this by analysing the electromagnetic absorption spectra of an exoplanet’s atmosphere as it transits its sun, seeking the presence of gases such as oxygen, methane, water vapour and ozone (a proxy for oxygen). We can look for similar artificial light signatures on the night side of exoplanets.

One good example of the nexus between global warming and local pollution is ground-level ozone. To make matters worse, NOx contributes to the formation of ground-level ozone and secondary PM2.5, February 2020 – Explosion at the Marathon Los Angeles refinery , the West Coast’s largest refinery.

Principal Deputy Assistant Administrator for the Office of Air and Radiation. Ozone layer protection in the United States reaches an important milestone in 2020. Environmental Protection Agency (EPA) has been helping to protect and heal the Earth’s stratospheric ozone layer by phasing out ozone-depleting substances (ODS).
