Summary

Abstract:
Updated solar irradiance reconstruction. (See also Lean et al., 1995). Included are time series of annual mean irradiance from 1610 to 2000 of just the 11 year solar irradiance cycle, plus the 11 year cycle with a background component. See Lean (2000) for discussion of the amplitude of the background component. Because of the dependence of the Sun's irradiance on solar activity, reductions from contemporary levels are expected during the seventeenth century Maunder Minimum. New reconstructions of spectral irradiance are developed since 1600 with absolute scales traceable to spacebased observations. The long-term variations track the envelope of group sunspot numbers and have amplitudes consistent with the range of Ca II brightness in Sun-like stars. Estimated increases since 1675 are 0.7%, 0.2% and 0.07% in broad ultraviolet, visible/near infrared and infrared spectral bands, with a total irradiance increase of 0.2%. |
