Top: Updated SATIRE-S TSI composite (red dots for daily values and thick blue line for 180-day running means) in comparison to the earlier version by Yeo et al. (2014) (black dots for daily values and thick yellow line for 180-day running means). Bottom: Difference between the Yeo et al. (2014) and updated versions. Daily values are given by the red dots and the 180-day running means by the blue line. The dashed yellow line is a linear fit to the residuals. The RMS difference, linear correlation coefficient, and the trend of the residuals are listed in panel b. The dotted black line marks residuals of 0 Wm⁻². The right panel shows the histogram of the residuals in bins of 0.05 Wm⁻².
