But in the lower part of the atmosphere, the troposphere, ozone is a pollutant that can create respiratory problems. So monitoring tropospheric ozone is important for mitigating its effects. But sometimes, natural ozone from the stratosphere can make its way to the troposphere, confusing monitoring efforts. \n\nOne of these events is what I'm visualizing here. In April 2012, an area of fast-moving low pressure caused ozone-rich stratospheric air to descend, folding into tropospheric air near the ground. Winds pushed it in all directions, bringing stratospheric ozone to the ground in the Southwest. You can see this as a curtain of swirling air reaching to the ground in this visualization. The air is color-coded by altitude blue at 10 km, and red at sea level. \n\nAtmospheric scientists at NASA's Goddard Space Flight Center in Greenbelt, Md., set out to see if the GEOS-5 Chemistry-Climate Model could replicate the intrusion at 25-kilometer resolution. Indeed, the model could replicate small-scale features, including finger-like filaments, within the apron of air that descended over Colorado. To communicate the implications of this result most effectively to non-scientists, we created a volumetric visualization that replaced numerical data with animation. By making visible events that would otherwise have remain invisible to those without expertise and training, the animation allows policymakers and the public to immediately comprehend the nature of the problem, and hopefully make more informed decisions in addressing it.", "width": 180, "height": 320, "pixels": 57600 } }, { "id": 293323, "type": "media", "extra_data": null, "title": null, "caption": null, "instance": { "id": 456297, "url": "https://svs.gsfc.nasa.gov/vis/a000000/a004100/a004160/strato_ozone_intrusion_30sec.0001_thm.png", "filename": "strato_ozone_intrusion_30sec.0001_thm.png", "media_type": "Image", "alt_text": "Stratospheric Ozone Intrusion Long VersionThis video is also available on our YouTube channel.", "width": 80, "height": 40, "pixels": 3200 } }, { "id": 293320, "type": "media", "extra_data": null, "title": null, "caption": null, "instance": { "id": 456300, "url": "https://svs.gsfc.nasa.gov/vis/a000000/a004100/a004160/frames/1920x1080_16x9_30p/long/", "filename": "long", "media_type": "Frames", "alt_text": "Stratospheric Ozone Intrusion Long VersionThis video is also available on our YouTube channel.", "width": 1920, "height": 1080, "pixels": 2073600 } }, { "id": 293324, "type": "media", "extra_data": null, "title": null, "caption": null, "instance": { "id": 456301, "url": "https://svs.gsfc.nasa.gov/vis/a000000/a004100/a004160/strato_ozone_intrusion_30sec_1080.mp4", "filename": "strato_ozone_intrusion_30sec_1080.mp4", "media_type": "Movie", "alt_text": "Stratospheric Ozone Intrusion Long VersionThis video is also available on our YouTube channel.", "width": 1920, "height": 1080, "pixels": 2073600 } }, { "id": 293325, "type": "media", "extra_data": null, "title": null, "caption": null, "instance": { "id": 456302, "url": "https://svs.gsfc.nasa.gov/vis/a000000/a004100/a004160/strato_ozone_intrusion_30sec_1080.webm", "filename": "strato_ozone_intrusion_30sec_1080.webm", "media_type": "Movie", "alt_text": "Stratospheric Ozone Intrusion Long VersionThis video is also available on our YouTube channel.", "width": 1920, "height": 1080, "pixels": 2073600 } }, { "id": 293326, "type": "media", "extra_data": null, "title": null, "caption": null, "instance": { "id": 456303, "url": "https://svs.gsfc.nasa.gov/vis/a000000/a004100/a004160/frames/1920x1080_16x9_30p/long_w_cbar/", "filename": "long_w_cbar", "media_type": "Frames", "alt_text": "Stratospheric Ozone Intrusion Long VersionThis video is also available on our YouTube channel.", "width": 1920, "height": 1080, "pixels": 2073600 } }, { "id": 293327, "type": "media", "extra_data": null, "title": null, "caption": null, "instance": { "id": 456304, "url": "https://svs.gsfc.nasa.gov/vis/a000000/a004100/a004160/strato_ozone_intrusion_30sec_cbar_1080p30.mp4", "filename": "strato_ozone_intrusion_30sec_cbar_1080p30.mp4", "media_type": "Movie", "alt_text": "Stratospheric Ozone Intrusion Long VersionThis video is also available on our YouTube channel.", "width": 1920, "height": 1080, "pixels": 2073600 } } ], "extra_data": {} }, { "id": 341383, "url": "https://svs.gsfc.nasa.gov/4160/#media_group_341383", "widget": "Single image", "title": "", "caption": "", "description": "Colorbar", "items": [ { "id": 293328, "type": "media", "extra_data": null, "title": null, "caption": null, "instance": { "id": 456305, "url": "https://svs.gsfc.nasa.gov/vis/a000000/a004100/a004160/nile_ozone_height_cbar.png", "filename": "nile_ozone_height_cbar.png", "media_type": "Image", "alt_text": "Colorbar", "width": 1200, "height": 250, "pixels": 300000 } } ], "extra_data": {} }, { "id": 341384, "url": "https://svs.gsfc.nasa.gov/4160/#media_group_341384", "widget": "Video player", "title": "", "caption": "", "description": "SIGGRAPH Version

But near the surface, the same chemical is a man-made pollutant that can cause respiratory distress. Sometimes air from the upper atmosphere descends to lower altitudes, transporting ozone with it. Such events, known as stratospheric ozone intrusions, may lead to unexpected spikes in ozone levels within populated areas. The mysterious events often take place over elevated terrain in mountainous states like Colorado, Nevada and California. In April 2012, curtains of ozone plunged from the upper atmosphere and covered parts of the western United States. Using a high-resolution model, NASA scientists simulated the event, showing where high concentrations of ozone made contact with the ground. Watch the video to see the event unfold. || ", "release_date": "2014-05-06T00:00:00-04:00", "update_date": "2023-05-03T13:50:57.458525-04:00", "main_image": { "id": 455442, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a011500/a011532/cover-1920.jpg", "filename": "cover-1920.jpg", "media_type": "Image", "alt_text": "Ozone descends to Earth’s surface, with consequences for air quality.", "width": 1920, "height": 1080, "pixels": 2073600 } } ], "sources": [], "products": [], "newer_versions": [], "older_versions": [], "alternate_versions": [] }
