| - | Multiple reconstructions of annual total solar irradiance are 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 WLS modern values. | + | Multiple reconstructions of annual total solar irradiance are [[https://pmip3.lsce.ipsl.fr/share/design/lm/solar_Dec21.tar.gz | provided]].

| Sensitivity experiments for the model response to the Pinatubo eruption yield an average global temperature change (0.4 K) comparable to observations.
