 ==== Total Solar Irradiance ==== ==== Total Solar Irradiance ====
  
 +Multiple reconstructions of annual total solar irradiance are [[https://​pmip3.lsce.ipsl.fr/​share/​design/​lm/​solar_Dec21.tar.gz | provided]]. These are designed to either fit smoothly with the reconstructions used in the post-1850 CMIP5 simulations (Wang, Lean and Sheely (2005)), or to explore independent estimates of the long term solar trends. Each series has an 11 year solar cycle throughout the time series (synthetic for pre-1610, based on a relationship between cycle magnitude and long-term TSI) and comes with an estimate of the spectral changes (as a function of the TSI anomaly). Each reconstruction is calibrated to the [[http://​www.geo.fu-berlin.de/​en/​met/​ag/​strat/​forschung/​SOLARIS/​Input_data/​CMIP5_solar_irradiance.html | WLS modern values]]. See the [[https://​pmip3.lsce.ipsl.fr/​share/​design/​lm/​README.txt | README.txt]] file for details of filenames and formats. ​

 +=== Wang, Lean and Sheely (WLS): 1610-2000 CE ===
 +
 +Spectral reconstruction based on a flux transport model of the open and closed flux using the observed sunspot record as the main input. This comes in two versions, A) a "​no-background"​ version that just has TSI variations similar to that seen over a solar cycle today, and B) a "with background"​ version with longer term trends in the solar minimum. ​
