Solar Irradiance Reconstruction (Lean, 2004)Entry ID: NOAA_NCDC_PALEO_2004-035
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%.
