This depleted region is known as the “ozone hole”.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 (a unit of measure for total ozone.) 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 direct measurements over Antarctica, a column ozone level of less than 220 Dobson Units is a result of the ozone loss from chlorine and bromine compounds.This hyperwall-ready series shows the recent status of the ozone layer over the Antarctic, with a focus on the ozone hole.

To help solve the global depletion of ozone, the international community regulated CFC production and consumption by adopting the Montreal Protocol in 1987.

NPP's second observation was farther west, close to Chelyabinsk, because the spacecraft's orbit moves from east to west. The third observation of the plume occurred the day following the event. The OMPS instrument could only see the plume during the daytime, and the NPP orbit had progressed westward away from the plume and into night by the time it was again over the plume.The OMPS Limb instrument observations are made by looking backward (relative to NPP's orbit) toward the Earth's limb.

NPP provides scientists and weather forecasters with critical continuity of data allowing them to study long-term climate changes and provide improved weather forecasts. The highly accurate five instruments on board NPP have already proven to deliver an exceptional quality of data thus continuing the legacy of satellites like Terra and Aqua.Shortly after local sunrise on February 15th of 2013, a meteor as big as a building reached Earth’s atmosphere and produced a massive explosion above Chelyabinsk, a densely populated Russian metropolis. The highly sensitive OMPS instrument on board NPP observed the plume from the explosion 1,100km eastward. Scientists used the data from this first observation and ran two NASA models to project the path of the plume. The results show that the plume’s higher layer would move ahead of the lower layer due to the difference in wind velocity at higher and lower altitudes. The models also showed that the plume would circumnavigate the entire globe and return to Chelyabinsk by February 19th, 2013. As more OMPS observations came in, it was clear that they coincided with the projected path perfectly. The results from this study proved the accuracy of the models as well as the unprecedented sensitivity of the OMPS instrument. The OMPS instrument was able to detect remains of the plume months after the initial explosion, which helped scientists track and study the plume for a long period of time. Since the Earth is constantly impacted by meteoric debris, an instrument like OMPS gives the scientists hope that in its 5-year design lifetime, they will better understand the effect of meteors and particles on the stratosphere, as well as the chemistry of our stratosphere and atmospheric ozone layer. || ", "hits": 105 }, { "id": 10824, "url": "http://svs.gsfc.nasa.gov/10824/", "result_type": "Produced Video", "release_date": "2011-09-22T00:00:00-04:00", "title": "A World Without The Montreal Protocol", "description": "A week ago marked the 24th anniversary of the signing of the Montreal Protocol, a landmark piece of legislation that began phasing out the production of ozone-depleting chemicals called chlorofluorocarbons (CFCs).

Continued monitoring of polar ozone levels helps researchers gain a better understanding of how the planet's climate may be changing. The following animation shows how ozone loss at the south pole has grown since the mid-80s. Early readings over Antarctica indicate little or no ozone depletion beyond naturally predicted levels.
