the enhanced UV radiation intensity due to global depletion of stratospheric ozone
and the increased cumulative sun-exposure of the public, are of major concern due to the deleterious health-associated effects of increased exposure to UV radiation.
The significant depletion of the stratospheric ozone
layer, which shields the earth from much of the biologically effective solar ultra-violet radiation, is mainly due to anthropogenic activity on the earth.
The ESAt develops in five research areas: radiopropagation, stratospheric ozone
and ultraviolet, air pollution and meteorology, atmospheric aerosols and characterization of biotechnological applications.
Price Chopper joins other GreenChill grocery partners such as Food Lion, Giant Eagle, and Harris Teeter, in pledging to surpass regulatory requirements by creating an inventory of current refrigerant emissions that affect climate change and the stratospheric ozone
layer, and then setting reduction targets for those emissions.
Topics covered include steady- and non-steady-state modeling, chemical kinetics, stratospheric ozone
, photochemical smog, the greenhouse effect, carbonate equilibria, the application of partition coefficients, pesticides, and toxic metals.
In 1986 the discovery by British researchers of a decline in stratospheric ozone
over Antarctica prompted the beginning of work there by teams from NOAA, Nasa and two American universities.
2]O] emissions to the atmosphere, which impact the greenhouse effect and stratospheric ozone
has received a Stratospheric Ozone
Protection Award given by the U.
CFCs are the main source of man-made stratospheric chlorine, largely responsible for global and Antarctic stratospheric ozone
depletion over the past 25 years.
Two recent studies indicate that the Montreal Protocol, a 1987 treaty designed to protect the eroded stratospheric ozone
layer, is finally beginning to work.
European Parliament and Council Regulation (EC) 2037/2000 of June 29, 2000 on substances that deplete the ozone layer aims to curb and eventually phase out the use of substances that deplete stratospheric ozone
GFDL conducts leading-edge research to expand the scientific understanding of many topics, including weather and hurricane forecasts, El Nino prediction, stratospheric ozone
depletion, and global warming.
This was accomplished by removing the hydrochlorofluorocarbons (HCFC) blowing agent, which is a known cause of stratospheric ozone
depletion, and replacing it with a hydrocarbon (HC) blowing agent.
SunWise Partner Schools sponsor classroom and schoolwide activities that raise children's awareness of stratospheric ozone
depletion, UV radiation, and simple sun safety practices.
Polluting ozone - not stratospheric ozone
which blocks UV rays - is an air pollutant which is formed by the decomposition of primary polluting agents such as nitrogen oxides and volatile organic compounds.
