Antarctic Ozone Hole Getting Smaller
2012-10-25 05:04:49

[ Watch the Video: 2012 Ozone Hole Max ] April Flowers for redOrbit.com - Your Universe Online According to data from NASA and National Oceanic and Atmospheric Administration (NOAA) satellites, the average area covered by the Antarctic ozone hole this year was the second smallest in the last 20 years, which scientists attribute to warmer temperatures in the Antarctic lower stratosphere. The ozone reached its maximum size for the 2012 season on September 22. On this date, it covered...

Ozone Suite On Suomi NPP Continues More Than 30 Years Of Ozone Data
2012-02-24 04:33:51

A new satellite instrument suite is now sending back detailed information about the health of the Earth's ozone layer, the shield that protects the world´s population from harmful levels of the sun's ultraviolet radiation. The Ozone Mapper and Profiler Suite, or OMPS, is one of five new instruments flying aboard NASA's Suomi National Polar-orbiting Partnership satellite (NPP), which was launched on Oct. 28, 2011. Suomi NPP is the result of a partnership between NASA, the National...

New Data Shows Antarctic Ozone Hole Still Remains

[ Watch the Video ] The Antarctic ozone hole, which yawns wide every Southern Hemisphere spring, reached its annual peak on Sept. 12. It stretched to 10.05 million square miles, the ninth largest ozone hole on record. Above the South Pole, the ozone hole reached its deepest point of the season on Oct. 9, tying this year for the 10th lowest in this 26-year record. NASA and the National Oceanic and Atmospheric Administration (NOAA) use balloon-borne instruments, ground-based instruments...

Scientists Detect First-Ever Arctic Ozone Hole
2011-10-03 05:19:46

A team of international researchers, led by NASA scientists, has discovered an unprecedented loss of protective ozone in the atmosphere above the Arctic this year, according to various media reports published on Sunday. That phenomenon, according to an AFP article, has led to the formation of an ozone hole five times the size of the state of California. It marks the first time that ozone loss in the Arctic region has matched ozone loss above Antarctica, both they and Postmedia News are...

The year is 2065. Nearly two-thirds of Earth's ozone is gone -- not just over the poles, but everywhere. The infamous ozone hole over Antarctica, first discovered in the 1980s, is a year-round fixture, with a twin over the North Pole. The ultraviolet (UV) radiation falling on mid-latitude cities like Washington, D.C., is strong enough to cause sunburn in just five minutes. DNA-mutating UV radiation is up 650 percent, with likely harmful effects on plants, animals and human skin cancer rates....

Sweden's ozone layer was thicker in February that it has been in decades, according to a report released Tuesday from the Swedish Meteorological Institute (SMHI). The measurements show a dramatic reversal from last year, when the ozone layer was the second-thinnest on record. The institute obtained measurements in February at its station in Norrkoeping, near Stockholm, which showed the ozone layer was 426 Dobson units (DU), the thickest since recordings began there in 1988.  And a record...

The 2008 ozone hole "“ a thinning in the ozone layer over Antarctica "“ is larger both in size and ozone loss than 2007 but is not as large as 2006. Ozone is a protective atmospheric layer found in about 25 kilometers altitude that acts as a sunlight filter shielding life on Earth from harmful ultraviolet rays, which can increase the risk of skin cancer and cataracts and harm marine life. This year the area of the thinned ozone layer over the South Pole reached about 27 million...

WASHINGTON -- The Antarctic ozone hole is back to an average size, shrinking about 16 percent from last year's record high, NASA said Friday. But it's still the size of North America. The ozone hole in mid-September reached a maximum size of 9.7 million square miles, down from its peak of 11.5 million square miles last year, said NASA atmospheric scientist Paul Newman. Human produced gases, containing chlorine and bromine, damage the Earth's protective ozone layer, forming a hole over the...
