        "http://www.w3.org/2000/01/rdf-schema#comment" : [ "The ozone-oxygen cycle is the process by which ozone is continually regenerated in the Earth's stratosphere, all the while converting ultraviolet radiation (UV) into heat. In 1930 Sydney Chapman resolved the chemistry involved.  The process is commonly called the Chapman cycle by atmospheric scientists.Most of the ozone production occurs in the tropical upper stratosphere and mesosphere. The total mass of ozone produced per day over the globe is about 400 million metric tons." ] ,
