Business / Agriculture / Montreal Protocol On Ozone Depleting Substances: An international agreement, to which the U.S. is a signatory, for controlling emissions of chemicals that deplete stratospheric ozone (including methyl bromide). The Clean Air Act Amendments of 1990 c MORE

Ozone (O3)

Business / Agriculture / Ozone (O3): A highly reactive molecule composed of three oxygen atoms. Environmentally, ozone is important in two completely separate contexts—one, as a naturally occurring screen of harmful radiation in the ou MORE

Ozone Layer

Science / Weather / Ozone Layer: An atmospheric layer that contains a high proportion of oxygen that exists as ozone. It acts as a filtering mechanism against incoming ultraviolet radiation. It is located between the troposphere and MORE


Science / Weather / Stratosphere: The layer of the atmosphere located between the troposphere and the mesosphere, characterized by a slight temperature increase and absence of clouds. It extends between 11 and 31 miles (17 to 50 kilom MORE


Science / Weather / Ultraviolet: Electromagnetic radiation that has a wavelength shorter than visible light and longer than x-rays. Although it accounts for only 4 to 5 percent of the total energy of insolation, it is responsible for MORE

Ives (Noir)

Life Style / Wine Grapes / Ives (Noir): Early 19th century American labrusca grape discovery used to produce red wines strongly 'foxy' in flavor. Highly vulnerable to Ozone gas pollution which causes diminished vigor and productivity. Shoul MORE
