WebAug 18, 2024 · Combining older sunspot measurements with modern satellite observations, scientists have put together estimates of the sun’s output – called Total Solar Irradiance, or TSI – for the past 400 years. There is still some debate around how much solar output changed in the past, with some reconstructions suggesting more variation than others. WebThe solar constant can fluctuate by ~0.1% over days and weeks as sunspots grow and dissipate. The solar constant also drifts by 0.2% to 0.6% over many centuries, according …
