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%. # # # # FUNDING SOURCE: NASA, USA. # GEOGRAPHIC REGION: Global # PERIOD OF RECORD: 1610 - 2000 AD # # # # DESCRIPTION: # 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. # # # # # DATA: # # Calculation of TSI from calc_tsi_ann.pro # Mon Apr 2 15:18:18 2001 # # YEAR | 11yrCYCLE |
