Yes, this is true. About 20 km above is the ozone layer.
Ozone layer is approximately 20 to 30 kilometres (12 to 19 mi) above Earth, though the thickness varies seasonally and geographically.
Ozone is concentrated at 20-40 km above earth with highest concentration 6-8 parts per million. It is present in the stratosphere of the earth's atmosphere.
The stratosphere region of the atmosphere contain the highest concentration of ozone. It is present in the form of ozone layer.
