An animation showing the ozone layer shielding our planet from the sun's intense ultraviolet radiation. Ozone absorbs nearly all of the biologically damaging UV radiation from the sun. ||

From 1979 to 1993, the average amount of ozone in the stratosphere has decreased by about 5%. || Graph of total ozone in the stratosphere from 1979 to 1993 || a000828.00010_print.png (720x480) [447.7 KB] || a000828_thm.png (80x40) [4.3 KB] || a000828_pre.jpg (320x242) [8.9 KB] || a000828_pre_searchweb.jpg (320x180) [49.9 KB] || a000828.webmhd.webm (960x540) [3.5 MB] || a000828.mp4 (640x480) [1.9 MB] || a000828.dv (720x480) [57.9 MB] || a000828.mpg (352x240) [2.0 MB] ||

This animation shows the total ozone as measured by Earth Probe TOMS since the earliest measurements by that instrument. Days for which the instrument collected little or no data are skipped. ||

This animation was created for an exhibit at the National Space Centre in Leicester, England. ||

During the winter of 2000, Arctic ozone levels reached their lowest point in eight years at an altitude of nearly 60,000 feet. Concentrations dropped more than 50 percent from average. ||

The evolution of ozone over the Arctic as shown through measurements of average ozone for March for the years 1979 through 1999, excluding 1995 and 1996. These measurements were made by the TOMS instruments on Nimbus-7, Meteor-3 and Earth Probe. Dark blue represent regions of low ozone and red represents regions of high ozone. || a000711.00005_print.png (720x480) [493.8 KB] || a000711_thm.png (80x40) [4.2 KB] || a000711_pre.jpg (320x242) [7.0 KB] || a000711_pre_searchweb.jpg (320x180) [54.4 KB] || a000711.webmhd.webm (960x540) [1.2 MB] || a000711.dv (720x480) [67.5 MB] || a000711.mp4 (640x480) [3.7 MB] || a000711.mpg (352x240) [1.9 MB] ||

This animation illustrates the movement of tropical air masses bringing tropospheric ozone into the northern temperate latitudes. ||

Researchers have discovered that smoke and smog move in different ways through the atmosphere. A series of unusual events several years ago created a blanket of pollution over the Indian Ocean.In this animation, significant smog or tropospheric ozone is represented by red and green and regions of significant smoke index are in shades of white and gray. ||

The fires that raged across southern Africa in August and September of 2000 produced a thick 'river of smoke' that observers compared with the aftermath of the Kuwaiti oil fires in 1991. NASA-supported studies currently underway on the event will contribute to improved air pollution policies in the region and a better understanding of its impact on climate change. ||
