SOLCON
Definition
- The objectives of the Solar Constant (SOLCON) experiment on the Atmospheric Laboratory for Applications and Science (ATLAS) were: (1) to measure the absolute value of the solar constant to +/- 0.1%, and (2) to measure long-term variations in the solar constant. The SOLCON instrument was an absolute self-calibrating radiometer. The radiometer had two channels which enabled the detection of and compensation for any degredation of the black surfaces, and the determination in space of the self-consistency of the radiometric system. Radiation measurements were made by using a heat balance system automatically driven by a feedback system. The two sensors were independently shuttered. The radiometer produced solar measurements with an accuracy of better that 0.05 %. The SOLCON instrument was flown on Spacelab 1 and on all three ATLAS missions. (en)
