Ozone Hole Over Antarctica Has Shrunk, Split in Two AP Graphic shows southern hemisphere with ozone in the air measured in Dobson units. Tuesday, October 01, 2002 WASHINGTON — The ozone hole over Antarctica is markedly smaller this year than in the last few years and has split in two, government scientists reported Monday. The so-called "hole," actually an area of thinner than normal ozone, was measured at 6 million square miles (15.6 million square kilometers) in September. That compares with around 9 million square miles (23.4 million square kilometers) on September measurements over the last six years, according to researchers at the National Oceanic and Atmospheric Administration and National Aeronautics and Space Agency.

While ozone at ground level is considered a pollutant, the layer of ozone high in the stratosphere is vital to life because it blocks dangerous radiation coming from the sun. Thinning of the ozone layer could lead to a rise in skin cancer, experts warn. Aerosols and other chemicals are blamed for the thinning, and treaties banning those ingredients are expected to help the layer recover over time. This year's improvement was attributed to warmer than normal temperatures around the edge of the polar vortex, or circular wind pattern that forms annually in the stratosphere over Antarctica, according to Paul Newman, a lead ozone researcher at NASA's Goddard Space Flight Center.

UV radiation is known to be a significant risk factor for skin cancers, eye cataracts, and immune system suppression. http://sedac.ciesin.org/ozone/

Welcome to the Socioeconomic Data and Applications Center's ( SEDAC ) home page for the Stratospheric Ozone and Human Health Project. Stratospheric ozone protects the Earth's surface from high levels of biologically damaging ultraviolet (UV) radiation, which is known to be a significant risk factor for skin cancers, eye cataracts, and immune system suppression. Due to the current downward trends in total column ozone at mid- and high-latitudes, the expected increase in UV exposure as a result of this ozone loss may pose a significant health risk in the future. The purpose of this site is to provide data and resources in the areas of ultraviolet (UV) radiation, ozone, and human health impacts of UV exposure for use by researchers, educators, government officials, health providers, students, and the general public.

Welcome to Mike's Ozone resource These pages provide links to Ozone data sources and UK UV. O3 values calculated by Mike made use of TOVS data (corrected as shown) until May 2005. From May 2005 TOAST smoothed GRIB data is available but this does not fit well with TOVs - No futher local charts produced. Spreadsheet bar graphs, 56N 5W data, NW Europe graphics, comparison with average (dist.gif) and ozone hole value (ho220.gif) were calculated by Mike Trigger mainly using GRaDS for the PC. Ozone values are based on 1 deg TOVS GRIB data. This data was chosen because it estimates Ozone during the polar darkness whereas the available near real time TOMS data requires daylight to obtain O3 values. TOAST data used following demise of TOVS in MAY 2005. DATA changes for TOVS: 1 AUGUST 2001 CPC TOVS DATA NOAA14 TO NOAA 16. This change according to Mike resulted in a decrease in averaged OZONE values by about 3%. TOAST data from May 05 used uncorrected, combines TOVS and backscatter UV data. TOVS values appeared to be lower than GOME, TOMS and other NOAA sources. The cause may be the method of calculation of the total ozone and possibly related to the NOAA 14 night time cold temperature bias. The TOVS Total Ozone algorithm was changed June 4, 2003 to eliminate low ozone values caused by cirrus contamination. This change will be most noticable in the tropics (source NOAA).

CIESIN Thematic Guides OZONE DEPLETION AND GLOBAL ENVIRONMENTAL CHANGE Welcome to the CIESIN thematic guide on ozone depletion issues. The purpose of this guide is to help you find selected key documents that pertain to the issue of ozone depletion: causes, human and environmental effects, and policy responses. The 1985 report of the discovery of an "ozone hole" over Antarctica focused attention on the idea that humans can have a significant impact on the global environment. This discovery, along with evidence that ozone is being lost at nearly all latitudes outside the tropics, has prompted much research into the causes of ozone depletion and the biological effects of increased ultraviolet radiation exposure. The potential effects on humans and the environment have led to international resolutions designed to gradually phase out production of ozone-depleting substances. As a result, the scientific and industrial communities have collaborated to find safe and economical replacements for chlorofluorocarbons (CFCs), the manmade chemicals implicated in ozone loss. This guide contains an Overview that provides general background on key concepts and issues related to ozone depletion. In addition, four subsections explore selected topics in greater detail:
