A team of Chinese researchers developed an innovative model to predict high concentrations of ground-level ozone.

The heatwave that brought 100-degree temperatures to the Philadelphia region in June also brought warnings that the air ...

When a satellite disintegrates in the upper atmosphere, it does not just disappear. Rather, it deposits a record of aluminum ...

Starlink already accounts for 40% of all the satellites ever launched, and each one releases harmful aluminum oxides when ...

The ozone layer plays a critical role in shielding the Earth from harmful ultraviolet (UV) radiation. Over the past few decades, human activities have ...

Scientists measured a typical thickness of the ozone layer over the Antarctic back in 1979 at around 225 Dobson Units. At its lowest point, in 2006, the ozone concentration over the Antarctic got ...

The ozone layer still has a long way to go until it is recovered. On October 5 this year (pictured) the layer reached a thickness of just 109 Dobson units, less than half the pre-1979 average ...

While the area of the ozone hole is an important measure, another is its depth. The concentration of ozone in the atmosphere is expressed in Dobson Units (DU), with the global average value for ozone ...

On March 12, the ozone layer also hit a new record thickness of 499 DU. After peaking in March, ozone layer levels remained well above average - breaking records for monthly averages in May, June ...

World Ozone Day, observed annually on September 16, aims at emphasising the critical role of the ozone layer in safeguarding the planet. Established by the United Nations (UN) in 1994, this day marks ...
