The long wavelength end set at 350 nm was associated with the atmospheric cut off by the atmospheric ozone absorption and other issues affecting the efficiency of ground based instruments.

Since methyl bromide had a short atmospheric lifetime, reductions in its use would have an immediate effect on ozone depletion.

Simultaneous monitoring will be carried out of atmospheric pollutants including ozone, PM10, PM2.5, nitrogen dioxide and organic and elemental carbon.

In addition, the ERS 2 mission contains the global ozone monitoring experiment (GOME), which provides atmospheric chemistry measurements (ozone and other gases) and an improved ATSR instrument that includes three visible channels.

The goal of this effort in the Pacific was to obtain in situ measurements of atmospheric trace gases related to stratospheric ozone.

Provide financial support to maintain both ground based and space borne measurement capabilities for climate and ozone related trace gases and atmospheric parameters.

Various atmospheric effects of climate change (e.g., cloud cover, aerosol abundance, albedo, temperature) on ground level UV may actually be larger than ozone induced effects.

Economic expansion has resulted in increases in atmospheric nitrous oxide and methane, ozone depletion, increases in great floods, damage to ocean ecosystems, including nitrogen runoff,

The effectiveness of the provisions of the Montreal Protocol and its Amendments has been clearly observed in the declining atmospheric abundances of many ozone destroying species.

Further research is needed on the response of ground level UV to changes in ozone, as well as to climate driven changes in other atmospheric parameters.

M. Atmospheric studies NASA apos s and NOAA apos s efforts to monitor ozone depletion continued to reflect the effects of the Mount Pinatubo eruption in June 1991.

Understanding atmospheric change requires an integrated system for collecting data on a wide array of parameters, including greenhouse gases, ozone, solar radiation, precipitation chemistry, aerosols, reactive gases and meteorology.

GAW serves as an early warning system to detect further changes in atmospheric concentrations of greenhouse gases, changes in the ozone layer and in the long range transport of pollutants, including acidity and toxicity of precipitation as well as of atmospheric burden of aerosols (dirt and dust particles).

The Subcommittee noted the important contribution of meteorological and atmospheric research satellites for studying global climate change, the greenhouse effect, the degradation of the ozone layer and other global environmental processes.

As a result of the successful implementation of the Montreal Protocol and its amendments, the atmospheric concentration of chlorofluorocarbons (the man made chemicals that destroy stratospheric ozone) has generally begun to decline.

The data is fundamental to our understanding of contemporary processes of global relevance such as ozone depletion, atmospheric pollution, climate change, the melting of ice shelves and glaciers and sea level rise.

The Subcommittee noted the important contribution of meteorological and atmospheric research satellites to studying global climate change, the greenhouse effect, the degradation of the ozone layer and other oceanic and global environmental processes.

In achieving the above specified objectives, LAPAN has conducted various activities comprising atmospheric research, ozone observations, air pollution monitoring, and research on solar physics, the solar terrestrial relationship, the ionosphere and the upper atmosphere.

The Microwave Limb Sounder (MLS) on the Upper Atmosphere Research Satellite (UARS launched in 1991) continued, meanwhile, to make unprecedented measurements of global chlorine monoxide (ClO) concentration, observing the spatial relationships of ClO, ozone, temperature and other atmospheric variables.
