SAGE III on ISS role in climate processes. water vapor measurements will provide important contributions on the long-term effect of this green house gas. Ozone research has remained at the forefront of atmospheric science for many years because stratospheric ozone shields the Earth's surface (and its inhabitants) from harmful ultraviolet radiation. Since recent declines in stratospheric ozone have been linked to human activity, accurate long-term measurements of ozone remain crucial. It is important to monitor ozone levels in the lower stratosphere and upper troposphere since observed trends are the largest and most poorly understood at those altitudes. SAGE III's high vertical resolution and long-term
Atmospheric Radiation Measurement Climate Research Facility Atmospheric Radiation Measurement Climate Research Facility The Atmospheric Radiation Measurement Climate Research Facility (ARM Climate Research Facility) is a United States Department of Energy scientific user facility for the study of global climate change by the national and international research community. The ARM Climate Research Facility consists of global observation sites and research aircraft that measure radiative properties of the atmosphere, particularly cloud and aerosol formation processes. Continuous data from these sites, as well as supplemental data obtained through intensive field research campaigns, are available to scientists online through the ARM Data Archive. ARM is collaboratively managed by nine DOE
