The "thickness" of the ozone layer - that is, the total amount of ozone in a column overhead - varies by a large factor worldwide, being in general smaller near the equator and larger as one moves ...

He had calculated that if all the ozone in the atmosphere were brought down to the Earth's surface, it would form a layer only about 3 mm thick. Becoming rather fond of this analogy, he converted ...

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 ...

Scientists measure the thickness of the ozone layer using a measurement called Dobson units where anything less than 220 Dobson units (DU) is considered to be an ozone hole.

F or the first time in 30 years, the gaping hole in the ozone layer above Antarctica is showing signs of healing.. Every year since it was discovered in 1985, scientists have watched the hole grow ...

This year's Antarctic ozone hole is the biggest ever, government scientists said Thursday. The so-called hole is a region where there is severe depletion of the layer of ozone — a form of oxygen ...

That shouldn’t be confused with the ozone layer in Earth’s upper atmosphere, which shields us from much of the sun’s ultraviolet radiation. Ground-level ozone, however, causes serious health problems.

In such a case, the United States could see a prolonged and significant decrease in ozone layer thickness - upwards of 15 to 25 percent in the highest halogen scenario modeled.

The FLI award harks back to a crisis that unnerved — and galvanized — humanity in the 1980s and ’90s.The ozone layer reduces how much radiation makes it to the surface of the Earth.
