As of this year, the levels of ozone-depleting chemicals in the stratosphere reached a major milestone on the path to recovery, dropping by more than half of what's needed for the ozone layer to ...

Stratospheric particles can shape the ozone layer Remember the ozone layer? If you were around in the 80s, that's likely the period you'd associated it with.

When close to the Earth's surface, the gas becomes a pollutant which is particularly dangerous for vulnerable people.View on ...

Wildfires release vast amounts of visible pollutants into the atmosphere that darken skies and push people indoors to avoid unhealthy air. But a ...

Ozone from the stratosphere - 10 miles above ground, plunged to the surface producing air quality alerts across southern Colorado on Monday. This is rare.

It is working, with the amount of ozone depleting chemicals in the atmosphere declining as expected," Shanklin said in an e-mail to USA TODAY.

Periods of extreme heat often lead to increased exposure to ground-level ozone, in addition to other negative effects. This ...

While the lower stratosphere experienced significant ozone depletion, the new study shows that the increase of smoke aerosol particles in the middle stratosphere enhances the heterogenous uptake and ...

Most of us don’t think about ozone as we go about our daily lives. Yet, this pale blue gas plays a huge role in keeping our planet habitable. There’s a layer of it in Earth’s stratosphere ...

Specifically, the radiative cooling caused by ozone depletion resulted in a stronger meridional temperature gradient between the mid and high latitudes in the upper stratosphere.

The recovery of the ozone layer has largely been put down to the Montreal Protocol which was introduced in 1987, and controls the amount of ozone-harming substances allowed in to the atmosphere.

While the lower stratosphere experienced significant ozone depletion, the new study shows that the increase of smoke aerosol particles in the middle stratosphere enhances the heterogenous uptake and ...
