The variations of the SSI are also wavelength dependent\, with larger relativ e variations in the EUV/UV and smaller variations in the visible and IR. T hese irradiance variations allow us to understand\, on the one hand\, the physics of the Sun as a star and\, on the other hand\, the key energy sour ce for the Earth's climate system. In this talk I will review the availabl e irradiance measurements\, composite datasets\, models and how the underl ying physics\, which drives the irradiance variations\, is implemented.\n\ nhttps://meetings.aip.de/event/24/contributions/360/ LOCATION:Haus H\, Telegrafenberg URL:https://meetings.aip.de/event/24/contributions/360/ END:VEVENT END:VCALENDAR
