Scientists collect the ozone concentration. This gives them an idea to check the thinning.
Ozone Layer
The Gasses trapped in the air bubbles of the ice in the different levels can tell them what the atmosphere was like when the ice was formed, each layer of ice represents an different year or group of years, it has been there a very long time and provides a timeline of the earths climate changes to help predict what we are going to see in the future. It takes a lot of samples to get a complete picture. Sometimes there wont be a good sample in a particular core for a given time period so multiple cores are needed.
Scientists hope the ozone layer will have recovered by around 2050.
which we live.
The Exosphere is the atmospheric layer the farthest distance from the lithosphere.
The troposphere is the closest to the Earth and most dense atmospheric layer

The atmospheric layer containing pollution is troposphere. It the nearest to earth.
mesosphere
Ozone Layer
The atmospheric layer containing water is troposphere. It contains water vapor.
Proposphere. This is the first layer about 12 km from the earth.This is 3/4 part of total atmospheric mass.Temparetutre are constant in this layer.

They form a layer called ozone layer which is found in the stratosphere.
