Magnitudes and timescales of total solar irradiance variability
@article{Kopp2016MagnitudesAT, title={Magnitudes and timescales of total solar irradiance variability}, author={Greg Kopp}, journal={Journal of Space Weather and Space Climate}, year={2016}, volume={6} }
The Sun’s net radiative output varies on timescales of minutes to gigayears. Direct measurements of the total solar irradiance (TSI) show changes in the spatially- and spectrally-integrated radiant energy on timescales as short as minutes to as long as a solar cycle. Variations of ~0.01% over a few minutes are caused by the ever-present superposition of convection and oscillations with very large solar flares on rare occasion causing slightly-larger measurable signals. On timescales of days to…

Reconstruction of total solar irradiance since 1995 presents reconstructions that add quiet-Sun TSI and its uncertainty to models that reconstruct the effects of sunspots and faculae and shows that the most likely upward drift inquiet-Sun radiative forcing since 1700 is between +0.07 and −0.13 W m−2.
