Ozone hole over Antarctica, what is it and what causes it?
Ozone destruction, leading to the ozone hole, becomes faster as temperature falls and the area gets isolated. -
Ozone in the troposphere, formation of polluting gases
Elevated ozone levels can be harmful for health and vegetation. Tropospheric ozone is not directly emitted, but produced by chemical reactions. -
Ozone layer destruction, regulation established in reaction to alarming discoveries
Since our natural protection against UV was threatened, the use of ozone destructing chemical substances is regulated in international agreements. -
Ozone molecules, mainly found in two layers of our atmosphere
Ozone in the stratosphere absorbs dangerous UV radiation to protect us, while ozone in the troposphere is poisonous substance. - Polar stratospheric clouds, microscopic ice crystals in the atmosphere
When temperatures fall below -80° C stratospheric particles turn into microscopic ice crystals that play an important role in ozone destruction. -
Stratosphere, atmospheric layer where temperature rises with altitude
The presence of ozone in the stratosphere causes temperature in the stratosphere to rise with altitude. -
Stratospheric aerosols, influence on Earth's climate
Small droplets, injected in the atmosphere during volcanic eruptions, play an important role in the physico chemistry of the stratosphere.
