SORCE (Solar Radiation and Climate Experiment)


SORCE (Solar Radiation and Climate Experiment) is an Earth observation satellite that carries four instruments to measure the total amount of solar radiation striking the atmosphere each day over a period of five years. Its data will allow the creation of a long-term climate record that will improve understanding of how changes in the Sun's intensity affect Earth's climate and the chemistry of the atmosphere. SORCE is part of NASA's EOS (Earth Observing System) and is be operated by the University of Colorado.
