Solar radiation

The full solar spectrum and its variability during a solar cycle, only measurable from space, are fundamental for the solar physics, the Earth’s climate and atmospheric chemistry.

BIRA-IASB contributes to the understanding of the Sun-to-Earth link by:

  • developing instrumentation to measure the spectral shape of sunlight and analyzing the instruments' observations
  • examining the solar radiation and its penetration to the surface of the Earth, as well as the long-term changes of these two parameters
