Linear correlation between iSSI and iSPS. The line of best fit is shown with an R2 of 0.942. The 95% confidence interval has an average value of 0.0105 Wm−2, so it is difficult to distinguish from the width of the line. The line with slope = 1 is shown as a dashed curve. The best-fit line has a slope less than one due to the decrease in the difference after 2021 shown in Figure 3.
