Atmospheric physics radiation (emitted by the sun) and terrestrial radiation (emitted by Earth's surface and atmosphere). Solar radiation contains variety of wavelengths. Visible light has wavelengths between 0.4 and 0.7 micrometers. Shorter wavelengths are known as the ultraviolet (UV) part of the spectrum, while longer wavelengths are grouped into the infrared portion of the spectrum. Ozone is most effective in absorbing radiation around 0.25 micrometers, where UV-c rays lie in the spectrum. This increases the temperature of the nearby stratosphere. Snow reflects 88% of UV rays, while sand reflects 12%, and water reflects only 4% of incoming UV radiation. The more glancing
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
