Its primary intended use is to determine the stratospheric ozone
layer thickness, which is calculated as a function of the relative intensities of the three narrow-band UVB readings utilizing an algorithm programmed into the instrument.
1974: Stratospheric ozone
depletion and solar ultraviolet radiation on earth.
In this section, we present the results of preliminary studies about the possible relationship between the surface ozone and the stratospheric ozone
measured at El Arenosillo.
This year's Climate and Stratospheric Ozone
Protection award winners are showing yet again that when they reduce greenhouse gas emissions, many good things happen," said Kathleen Hogan, director, EPA Climate Protection Partnerships Division.
Bromine is 50 times more efficient than chlorine at destroying stratospheric ozone
, and enters the atmosphere primarily as a pesticide called methyl bromide.
But he doesn't understand the science well, saying, for example, "By spraying deodorant at your armpit in your New York apartment" you could be "killing people" by contributing to stratospheric ozone
Decreasing amounts of stratospheric ozone
that partially protects the earth's surface from receiving cancer-producing UV radiation.
A University of California Irvine (UCI) study shows that the world's rice paddies emit methyl halide gases that contribute to stratospheric ozone
No one disputes that stratospheric ozone
recovery is one of the environmental movement's great success stories.
The EPA established the Stratospheric Ozone
Protection Awards in 1990 to recognize exceptional leadership, personal dedication and technical achievements in eliminating ozone-depleting substances.
Although the possible destruction of stratospheric ozone
had been hinted at in the 1970s, it was not until 1985 that the phenomenon was actually observed.
But 10 to 20 percent of the Sun's "extra" luminosity comes out in the ultraviolet, which stratospheric ozone
