Definition
- The objective of the Solar Spectrum Measurement (SOLSPEC) experiment was the measurement of absolute solar irradiances in the wavelength range from 180 to 3000 nm with an accuracy of 0.1% and measuring the variability of the solar irradiances in this wavelength range. The experiment consists of three double grating spectrometers covering the UV (180 to 370 nm), visible (350 to 900 nm) and IR (800 to 3000 nm) and an onboard calibration device. The three spectrometers use concave holographic gratings of 10-cm focal length with a spectral positioning accuracy of 0.01 nm. The onboard calibration device consists of two deuterium lamps, two tungsten ribbon lamps, and one hollow cathode lamp. The instrument is calibrated against a 3300 K black body and a set of tungsten ribbon lamps. SOLSPEC was flown on all three Atmospheric Laboratory for Applications and Science (ATLAS) missions.
