surface UV to geo-engineering of climate

Importance of very short-lived halogens for understanding the response of surface UV to geo-engineering of climate

annual changes in UV

A proposed method for geo-engineering climate involves the injection of sulfur into the tropical stratosphere. The resulting enhanced global stratospheric aerosol burden would reflect and scatter sunlight, reducing the Earth’s surface temperature and ultraviolet (UV) radiation intensity.  Chemical reactions on the surface of aerosol particles would enhance heterogeneous reactions and alter the ozone abundance, which would change surface UV radiation.
