"title": "The Story of Ozone Depletion",
"description": "The Antarctic ozone hole is caused by human-produced chlorine-containing chlorofluorocarbons (CFCs) and bromine-containing halons. These compounds had a variety of commercial uses, including hair sprays, refrigerants, and fire suppressants.This story about the cause of ozone depletion was originally developed for the NASA hyperwall, where nine different animations can be shown simultaneously. The animations shown here are derived from the Goddard Earth Observing System (GEOS) model and cover two periods. The first period is from August through November 2004, and the second is from December 2004 through March 2005. The first period animations are shown on this page. The second period animations may be downloaded through the Download links below.The chlorine compounds that destroy ozone have now been regulated under the international Montreal Protocol agreement. Because of this agreement, the ozone hole is projected to disappear around 2060-2070. NASA and the international community continue to monitor Antarctic ozone. || ",

"description": "These visuals were created in anticipation of the 2016 Korean United States Air Quality study (KORUS-AQ) field campaign which will combine observations from aircraft, satellties, ships and ground stations with air quality models to assess and monitor air quality acorss urban, rural and coastal areas.Ozone gas and particle pollution are two of the main factors that contribute to poor air quality around the world. While ozone gas located high in the stratosphere protects us from the sun’s harmful UV rays, pollution from cars and other human emissions near ground level can cause chemical reactions that lead to ozone formation near the surface. Breathing in high levels of ozone is also bad for human health, causing lung diseases and health impacts on sensitive populations such as children, the elderly and people with asthma. These visuals are showing the ozone that formed near the surface, or 'surface ozone', over the Korean peninsula in June 2013 according to the GEOS-5 Nature Run chemistry model data. Peak ozone in Korea occurs between April and June.Since Seoul is located on a peninsula, the metropolitan area and the pollution produced here are separated from other sources of emissions. In addition, Seoul’s human-produced emissions are concentrated in its urban areas but are surrounded by more rural agricultural areas. The contrast between urban and rural zones on the peninsula allow scientists to study and differentiate human and naturally-produced emissions and better understand how they interact chemically. Understanding the chemical reactions between urban and agricultural emissions is extremely important for improving models that forecast air quality. || ",

"title": "Stratospheric Ozone Intrusion",
"description": "Events called stratospheric ozone intrusions occur most often in spring and early summer, and can raise ground-level ozone concentrations in some areas to potentially unhealthy levels.This visualization shows one such event that occurred on April 6, 2012. On that day, a fast-moving area of low pressure moved northeast across states in the Western U.S., clipping western and northern Colorado. Ozone-rich stratospheric air descended, folding into tropospheric air near the ground. Winds took hold of the air mass and pushed it in all directions, bringing stratospheric ozone to the ground in Colorado and along the Northern Front Range.Atmospheric scientists at NASA's Goddard Space Flight Center in Greenbelt, Md., set out to see if the Goddard Earth Observing System Model, Version 5 (GEOS-5) Chemistry-Climate Model could replicate stratospheric ozone intrusions at 25-kilometer (16-mile) resolution. High-resolution models are possible due to computing power now capable of simulating the chemistry and movement of gasses and pollutants around the atmosphere and calculating their interactions.They show that indeed, the model could replicate small-scale features, including finger-like filaments, within the apron of ozone-rich stratospheric air that descended over Colorado on April 6, 2012. || ",
