Is there evidence that refrigerants are in the stratosphere?

Explanation:
Refrigerants such as chlorofluorocarbons are very stable in the lower atmosphere, so they can travel upward and reach the stratosphere. Their long lifetimes mean they persist for decades, allowing them to accumulate in the upper atmosphere. In the stratosphere, UV light breaks these molecules apart and releases chlorine, which can destroy ozone. Scientists have direct measurements from aircraft, balloons, and satellites showing trace amounts of refrigerants in the stratosphere, confirming their presence despite phased-out production. So there is clear evidence that refrigerants are in the stratosphere.
