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
Captain Video: Master of the Stratosphere group of crime-fighters known as the Video Rangers. He faces an interplanetary menace, as the evil dictator of the planet Atoma, Vultura (Gene Roth) and his lackey, the traitorous earth scientist Dr. Tobor (George Eldredge) are planning to conquer the earth. "Captain Video: Master of the Stratosphere" was the only serial adapted from television. It was one of Katzman's first forays into science fiction and was soon followed by "The Lost Planet. As produced by Sam Katzman, the serial had a production budget much larger than the famously small budget of the DuMont Television Network's live daily teleseries. The "Captain
