Solar Radiation and Climate Experiment Solar Radiation and Climate Experiment The Solar Radiation and Climate Experiment (SORCE) is a NASA-sponsored satellite mission that measures incoming X-ray, ultraviolet, visible, near-infrared, and total solar radiation. These measurements specifically address long-term climate change, natural variability and enhanced climate prediction, and atmospheric ozone and UV-B radiation. These measurements are critical to studies of the Sun, its effect on our Earth system and its influence on humankind. The SORCE spacecraft launched on January 25, 2003 on a Pegasus XL launch vehicle to provide NASA's Earth Science Enterprise (ESE) with precise measurements of solar radiation. SORCE measures the Sun's output using
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
