The patterns of soil moisture in response to the greening under different sea surface temperatures (SSTs). Spatial patterns of changes in soil moisture under three SST model forcings: a climatology mean SST; c La Niña SST; and e El Niño SST. To test the relationships of spatial patterns between greening and the resulting soil moisture changes, sensitivity analysis through linear regression is applied. The sensitivity of soil moisture changes ΔSM to greening indicated by ΔLAI is computed as \(\Delta \mathrm{SM}=\uptheta \cdot \Delta \mathrm{LAI}+\mathrm{c}\), where the ΔSM and ΔLAI come from the spatial patterns including a total of 163 pixels within Australia for each variable. The results are presented as the corresponding scatter plots of b, d, f under the climatology mean SST, La Niña SST, and El Niño SST, respectively
