NASA Ozone Watch: Latest status of ozone

· The area of the ozone hole is determined from a map of total column ozone. It is calculated from the area on the Earth that is enclosed by a line with a constant value of 220 Dobson Units. The value of 220 Dobson Units is chosen since total ozone values of less than 220 Dobson Units were not found in the historic observations over Antarctica prior to 1979. Also, from …

Ozone Layer - Our World in Data

Ozone concentrations are collected via satellite instruments as part of NASA’s Ozone Watch meteorological programme. Ozone concentrations are measured in Dobson Units (DU): this is number of molecules of ozone that would be required to create a layer of pure ozone millimeters thick at a temperature of 0 degrees Celsius and a pressure of 1 atmosphere. An ‘Ozone Hole’ would ...

Nasa Ozone Watch: Ozone hole facts

Ozone hole facts. These reactions convert the inactive chlorine reservoir chemicals into more active forms, especially chlorine gas (Cl 2).When the sunlight returns to the South Pole in October, UV light rapidly breaks the bond between the two chlorine atoms, releasing free chlorine into the stratosphere, where it takes part in reactions that destroy ozone molecules while regenerating the ...

Nasa Ozone Watch: Ozone facts

· NASA Ozone Watch Images, data, and information for atmospheric ozone Ozone Maps ... Ozone only screens about half of the UV-a radiation. Excessive UV-b and UV-a radiation can cause sunburn and can lead to skin cancer and eye damage. Solar ultraviolet radiation is largely absorbed by the ozone in the atmosphere—especially the harmful, high-energy UV-a and UV-b. The graph shows …

NASA GISS: Research Features: Ozone and Climate Change

· Interactions between ozone and climate naturally occur not only in the stratosphere, but also at the Earth's surface (troposphere). There are known chemical and physical aspects of ozone formation we can watch carefully as climate changes. Ozone forms in the troposphere by the action of sunlight on certain chemicals (photochemistry).

NASA - Discovering the Ozone Hole: Q&A With Pawan Bhartia

The recently launched Suomi-NPP satellite has a new generation ozone-monitoring instrument called OMPS. Copies of this instrument are planned for future satellites. Changes in the ozone hole now are not significantly driven by changes in CFCs, but instead driven by year-to-year changes in weather in the stratosphere. While the hole is no longer an issue from an environmental perspective, people continue …

Nasa Ozone Watch: Ozone hole history facts

· History of the Ozone Hole. Throughout the 20th century, discoveries and observations trickled in that would allow scientists to understand how human-made chemicals like chlorofluorocarbons create a hole in the ozone layer over Antarctica each spring. As early as 1912, Antarctic explorers recorded observations of unusual veil-type clouds in the ...
