  skos:definition """The SOLAR monitoring observatory (SOLAR) was an ESA science observatory mounted externally on the Columbus Laboratory, a module of the International Space Station. The primary goal of SOLAR is the (quasi-) continuous measurement of the solar "constant" in order to separate solar effects from human influence on climatology (in progress). SOLAR was launched on February 2008 aboard STS-122. It was originally composed of three scientific instruments: SOVIM (Solar Variability and Irradiance Monitor), SOLSPEC (Solar Spectral Irradiance Measurements), and SolACES. SOLSPEC and SolACES provided detailed measurements of the Sun's spectral irradiance from April 2008 to mid-February 2017 from 16 nm to 3 microns.
