The troposphere is the layer of the atmosphere closest to the earth. It extends from the ground to approximately 12km above sea level (though this varies with latitude and with the seasons). It contains around 75% of all the air in the atmosphere, and ...
Since the mid-1970s scientists have been concerned about the harmful effects of certain chlorofluorocarbons (CFCs) on the ozone layer. These CFC compounds are relatively inert and nontoxic, and humans found a use for them as cooling agents in refrigera...
Drag the map to explore the atmosphere! Turn elements of the map on and off using the buttons at the bottom. Each white spot represents 10 billion billion billion molecules of ozone.
This 3D map shows a 20 km x 20 km area of land and the air above it extending to an altitude of 100 km. Each floating particle represents 10 billion billion billion molecules of ozone. The area marked in orange indicates the ozone layer.
The ozone layer is a layer in the Earth's atmosphere containing high concentrations of ozone. It is typically said to exist between about 20 and 30km above the Earth's surface, but it does not have definite edges.

Keep Cool and Carry On
The Montreal Protocol has been keeping our planet cool for years by phasing out ozone-depleting substances that are also potent global-warming gases.
During this year's World Ozone Day on...
Co-Chair of the Scientific Assessment Panel of the Montreal Protocol, Prof. John Pyle, has been awarded the 2018 Davy Medal for pioneering leadership in understanding the depletion of the global ozone layer by halocarbons, particularly coupling between...
The refrigeration and air-condition sector may not immediately strike you as a particularly popular career choice for women – but you would be wrong.
More and more women are making the transition to this traditionally male-dominated industr...
The Ozone Secretariat has once again demonstrated its commitment to climate action by making its operations carbon neutral for the fourth consecutive year.
The Secretariat measured the carbon footprint of all meetings held and operations cond...
