The 2014 level of these substances over Antarctica has declined about 9 percent below the record maximum in 2000.“Year-to-year weather variability significantly impacts Antarctica ozone because warmer stratospheric temperatures can reduce ozone depletion,” said Paul A. Newman, chief scientist for atmospheres at NASA's Goddard Space Flight Center in Greenbelt, Maryland.Scientists are working to determine if the ozone hole trend over the last decade is a result of temperature increases or chorine declines.

This dataset shows tropospheric ozone, which is close to the ground and a component of pollution. This should be distinguished from high altitude (stratospheric) ozone which shields the Earth's surface from ultraviolet radiation.For more information about tropospheric ozone see the links below:http://www.nasa.gov/vision/earth/environment/ozone_resource_page.htmlhttp://www.ozonelayer.noaa.gov/science/basics.htm || ", "hits": 43 }, { "id": 3586, "url": "https://svs.gsfc.nasa.gov/3586/", "result_type": "Visualization", "release_date": "2009-03-17T00:00:00-04:00", "title": "What Would have Happened to the Ozone Layer if Chlorofluorocarbons (CFCs) had not been Regulated?", "description": "Led by NASA Goddard scientist Paul Newman, a team of atmospheric chemists simulated 'what might have been' if chlorofluorocarbons (CFCs) and similar ozone-depleting chemicals were not banned through the Montreal Protocol. The comprehensive model — including atmospheric chemical effects, wind changes, and solar radiation changes — simulated what would happen to global concentrations of stratospheric ozone if CFCs were continually added to the atmosphere.The visualizations below present two cases, from several different viewing positions: the 'world avoided' case, where the rate of CFC emission into the atmosphere is assumed to be that of the period before regulation, and the 'projected' case, which assumes the current rate of emission, post-regulation. Both cases extrapolate to the year 2065. || ", "hits": 232 }, { "id": 10255, "url": "https://svs.gsfc.nasa.gov/10255/", "result_type": "Produced Video", "release_date": "2008-06-10T00:00:00-04:00", "title": "Exploring Ozone", "description": "This short video combines dynamic ozone visualizations with an interview with leading atmospheric NASA scientist, Dr. Paul Newman.
