Possible impact of stratospheric polar ozone depletion on tropospheric climate
It has become a public concern that ozone depletion in the stratosphere would lead to increasing ultraviolet radiation on the surface. That stratospheric polar ozone depletion which likely has important impacts on atmospheric circulations and climate has also been one of important topics in climate...

It has become a public concern that ozone depletion in the stratosphere would lead to increasing ultraviolet radiation on the surface.
