We've tried to cover the subject areas our speakers focus on most. \n\nIf you're not seeing what you're looking for, there is a huge library of visualizations more localized or specialized in subject - please use the Search function above, and filter \"Result type\" for \"Hyperwall Visual.\"\n\n If you'd like to use one of these visualizations in your Hyperwall presentation, we'll need to know which element on which page. On the visualization's web page, below the visual you'd like to use, you'll see a Link icon next to the Download button. All we need is for you to click on that icon and include that link in your presentation Powerpoint/Keynote or visualization list.

            "description": "Total Column Ozone from EP-TOMS and MERRA-2 GMIThe ozone layer is Earth’s protection from harmful ultraviolet radiation. NASA has a long history of measuring total column ozone using a variety of instruments, typically with polar orbiting satellites measuring backscattered solar radiation. This produces near global coverage over the course of a day over the sunlit portion of Earth. Some missing data occurs between swaths, over the polar region during winter, and during satellite outages. This animation shows the evolution of daily composites of total column ozone as observed with Earth Probe Total Ozone Mapping Spectrometer (EP-TOMS), on the right panel, from July 1, 2002 to Oct. 31, 2002. On the left panel is the total column ozone from the MERRA-2 GMI simulation, with hourly time resolution over the same time period. MERRA-2 GMI is a Goddard Earth Observing System version 5 (GEOS-5) “replay” simulation at 0.5° (~50km) horizontal resolution, driven by MERRA-2 reanalyzed winds, temperature, and pressure, coupled to the comprehensive Global Modeling Initiative (GMI) stratosphere-troposphere chemical mechanism. This animation shows the onset of the Antarctic ozone hole formation during austral winter of the dynamically active 2002 season and its breakdown during spring. In September 2002, the Antarctic polar vortex split into 2 lobes following the first and only observed major stratospheric warming in the Southern Hemisphere over our observational record.  By combining NASA’s observations and chemistry simulations we have a clearer view of the evolution of Earth’s ozone layer over the recent past. || oman_toz_2002_pngs_1080.00001_print.jpg (1024x576) [117.1 KB] || oman_toz_2002_pngs_1080.00001_searchweb.png (320x180) [61.2 KB] || oman_toz_2002_pngs_1080.00001_web.png (320x180) [61.2 KB] || oman_toz_2002_pngs_1080.00001_thm.png (80x40) [6.0 KB] || oman_toz_2002_pngs_1080.webm (1920x1080) [10.5 MB] || oman_toz_2002_pngs_1080.mp4 (1920x1080) [187.7 MB] || ",

Since the 1960s, NASA scientists have worked with NOAA researchers to study the ozone layer, using a combination of satellite, aircraft and balloon measurements of the atmosphere.Things have been improving in the 30 years since the Montreal Protocol. Thanks to the agreement, the concentration of CFCs in the atmosphere has been decreasing, and the ozone hole maximum has been smaller since a record in 2006.From the ground and space, NASA science offers a unique perspective of Earth, helping to identify challenges and find solutions to benefit the planet. || ",

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. || ",

The ozone hole varies from twice to three times the size of the United States.3. Since the Montreal Protocol agreement in 1987, emissions have been regulated and ozone-depleting chemical levels have been slowly declining.4.

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. Satellite instruments monitor the ozone layer, and OzoneWatch uses their data to create the images that depict the amount of ozone. || ",

The size of this year’s hole was 24.1 million square kilometers (9.3 million square miles) — an area roughly the size of North America.With the increased atmospheric chlorine levels present since the 1980s, the Antarctic ozone hole forms and expands during the Southern  Hemisphere spring (August and September). The ozone layer helps shield life on Earth from potentially harmful ultraviolet radiation that can cause skin cancer and damage plants.The Montreal Protocol agreement beginning in 1987 regulated ozone depleting substances, such as chlorine-containing chlorofluorocarbons and bromine-containing halons. 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. An increase of stratospheric temperature over Antarctica would decrease the ozone hole’s area. || ",

In 1985, an extreme depletion of ozone over Antarctica was discovered—the so-called Antarctic ozone hole. It soon became clear that this drop in ozone was caused by man-made chemicals called chlorofluorocarbons (CFCs). To help solve the global depletion of ozone, the international community regulated CFC production and consumption by adopting the Montreal Protocol in 1987. Although this and subsequent actions have now effectively banned CFC production and put the ozone layer on a path to recovery, long-lived CFCs in the atmosphere continue to effect ozone levels to this day.

Parties to the Montreal Protocol reported zero new emissions between 2007-2012.However, new research led by Qing Liang at NASA's Goddard Space Flight Center in Greenbelt, Maryland, shows that worldwide emissions of carbon tetrachloride average 39 kilotons per year – approximately 30 percent of peak emissions prior to the international treaty going into effect.

These chemicals, also known by the trade name Freon, were common refrigerants and widely used in aerosol spray cans prior to the Montreal Protocol. In recent years, scientists have been using cutting-edge computer models of the atmosphere to ask a fascinating question: What would have happened to the ozone layer if nations had done nothing to limit the release of CFCs? The impact of inaction, the modeling shows, would have been ominous: increased rates of cancer, cataracts, and immune deficiency diseases are just a few of the consequences. By 2065, global ozone levels would drop to less than 110 Dobson units—a measure of the amount of ozone between the surface and space. (A healthy Dobson unit reading over Antarctica is around 275.) \"We wouldn't be able to go out much at all,\" says NASA scientist Paul Newman.

The process starts in the dark of Antarctic winter as sub-freezing temperatures give rise to large numbers of wispy, iridescent clouds located high over the continent, 80,000 feet up in a layer of air called the stratosphere. The clouds are key to the depletion of ozone because a cascade of ozone-depleting reactions, fueled by human-generated chlorofluorocarbons, halons and methyl bromide compounds, occur within them. When the sun shines over Antarctica in the spring, its rays release chlorine and bromine atoms from these chemicals in forms that attack ozone. The atoms eat away as much as 70 percent of the ozone layer, creating an \"ozone hole\" to form over the region. So far, the hole appears slightly larger than it was this time last year, but it won't reach its maximum size until mid-October. In the visualization below watch the ozone hole grow from July 1 to September 16, 2011. || ",

The average concentration of ozone in the atmosphere is about 300 Dobson Units; any area where the concentration drops below 220 Dobson Units is considered part of the ozone hole.  Each year the 'hole' expands over Antarctica, sometimes reaching populated areas of South America and exposing them to ultraviolet rays normally absorbed by ozone.   The data in these omages were acquired by the Ozone Monitoring Instrument on NASA's Aura satellite. On September 11, 2005, ozone thinning over Antarctica reached its maximum extent for the year at 27 millions of square kilometers.  On October 1, 2005 the minimum ozone value was recorded at 102 Dobson Units. || ",

            "description": "NASA has been monitoring the status of the ozone layer through satellite observations since the 1970s, beginning with the TOMS sensors on the Nimbus satellites. The latest-generation ozone-monitoring technology, the Ozone Monitoring Instrument (OMI), is flying onboard NASA's Aura satellite. The ozone hole is not technically a 'hole' where no ozone is present, but is actually a region of exceptionally depleted ozone in the stratosphere over the Antarctic.  The ozone hole begins to grow in August and reaches its largest area in depth in the middle of September to early October period. In the early years (before 1984) the hole was small because chlorine and bromine levels over Antarctica were low. Year-to-year variations in area and depth are caused by year-to-year variations in temperature. Colder conditions result in a larger area and lower ozone values in the center of the hole.  This animation shows total ozone in the Antarctic region along with the maximum ozone depth and size since the earliest measurements of Earth Probe instrument on the TOMS satellite.  This animation was created for an exhibit at the Smithsonium Museum. Data dropouts have been removed for the following times:  1998/12/14-31, 2002/08/03-11, 2003/11/28-2003/12/02.

Low ozone (less than 200 Dobson units) is depicted as regions of dark blue, with high ozone (greater that 330 Dobson units) depicted as yellow and red. The most visible and dynamic feature of the ozone distribution is the ozone hole that forms over Antarctica during September of each year. The amount of ozone in the stratosphere over Antarctica is reduced during this period due to unique atmospheric conditions which chemically reduce the amount of ozone in the region and prevent that ozone from mixing with the higher ozone concentrations just outside the hole. Ozone blocks harmful ultraviolet 'B' rays, and loss of statospheric ozone has been linked to skin cancer in humans and other adverse biological effects in plants and animals. This visualization explicitly shows the TOM ozone data coverage and does not interpolate data into regions of the Earth that the instrument did not observe. Since TOMS measures ozone by observing the characteristics of sunlight reflected from the Earth's surface, no measurements are available for the poles during the polar winter, i.e., around January for the North Pole and July for the South Pole. Also, there is an unobserved region between successive satellite orbits around the equator. Finally, the instrument has periods where technical issues make measurement impossible for a matter of hours or days. This visualization shows that the dynamics of the ozone layer remain visible despite these measurement issues. || ",

The animation on the left fully illustrated the data, imperfections and all, under the assumption that a presenter would have time to explain the animation in detail.  The animation on the right had all the data 'imperfections' removed by interpolation, under the assumption that the viewer would only have 20 or 30 seconds to look at it (on the evening news, for example) with only the briefest of explanations.  The problem was that, without explanation, a layman might interpret the region of missing data in the movie on the left to be the ozone hole, instead of the central blue region.

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. But as the 80s and 90s progress, a clear change in atmospheric chemistry takes place at the bottom of the world.
