In 2004, the size of the ozone hole was smaller than the average over the past decade, although the total amount of ozone destroyed, which relates to the size, depth and persistence of the ozone hole, was estimated to be much higher than most years in the past decade.

The Antarctic springtime ozone hole is one of the most dramatic manifestations of global change.

The term quot ozone hole quot describes a large area of intense ozone depletion that occurs over Antarctica during late August through early October and typically breaks up in late November.

That year, a large hole in the ozone layer over the Antarctic was detected, prompting Vienna Convention parties quickly to negotiate a graduated phase out of ozone depleting substances under the Montreal Protocol.

We can move things out of the stratosphere into the mesosphere, in principle solving the ozone problem.

Water is becoming scarce, there are holes in the ozone layer and, along with biodiversity, the Amazon is being destroyed.

The other problem is they're right in the ozone layer, and I'd prefer them above the ozone layer.

Trafficking in ozone depleting substances

The net effect of all those harmful actions was excess carbon dioxide and methane in the atmosphere, holes in the ozone layer over the North and South Poles and rising global temperatures.

WMO's World Ozone and Ultraviolet Data Centre (WOUDC), operated by the Meteorological Service of Canada in Toronto, is the primary repository of the world's ozone data.

Tropospheric Ozone Tropospheric ozone has just been recognized as a potentially important greenhouse gas.

Illegal trade in ozone depleting substances is controlled by the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer, which aims to gradually reduce and finally phase out all ozone depleting substances.

Future ozone concentrations are mainly driven by the changes in stratospheric halogen loading, with ozone recovery occurring after the peak of halogen loading.

There are a number of new unanswered questions with respect to expected ozone recovery and the interrelationship between ozone and climate change.

Scientists have determined that chlorine products from human activities, such as electronics manufacturing, air conditioning, and refrigeration, are a primary cause of ozone hole formation.

These agreements are hailed as great successes, and annual reports summarizing official statistics are published showing that the use of CFC continues to decrease. The content of chlorine (from decay of CFC s) in the stratosphere has leveled off, and two years ago the ozone hole over the Antarctic was the smallest in decades (and broken up into two).

Continue the implementation of ozonesonde standard operating procedures, and extend these procedures to other ozone and UV instrument types.

Where 2002 was not yet reported, 2001 reported data were used.
