Ozone–oxygen cycle Ozone–oxygen cycle The ozone–oxygen cycle is the process by which ozone is continually regenerated in Earth's stratosphere, 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. The global mass of ozone is relatively constant at about 3 billion metric tons, meaning the Sun produces about 12% of the ozone layer each day. And if
Zombies of the Stratosphere Man back-pack and helmet, used for the first time in this serial, is a two-way radio about the size of a lunchbox; Larry Martin wears it hanging heavily from his belt when dressed for flying. This radio is also seen in some stills of Cody in "". As most flying sequences are reused stock footage from earlier Rocket Man serials, the radio usually disappears when Commando Cody is in flight. Martin also uses an ordinary police revolver instead of the ray gun favored by Cody in earlier and later serials. "Zombies of the Stratosphere" was budgeted at $172,838, although the
