What is the layer of the atmosphere that is characterized by an increase in temperature due to the concentration of ozone?

The layer of the atmosphere characterized by an increase in temperature due to the concentration of ozone is the stratosphere. In this layer, ozone absorbs harmful ultraviolet (UV) radiation from the Sun, leading to a rise in temperature with altitude. This temperature inversion is crucial for protecting life on Earth from excessive UV exposure. The stratosphere lies above the troposphere and below the mesosphere.
