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.

The SOLAR instrument will dive back to Earth on Monday, January 13 2020 to burn up in the atmosphere over the Pacific Ocean.
Precise measurement of the solar spectrum outside the atmosphere and its variability.
