In a tomographic approach, we measure the cross-correlation between the CMBlensing reconstructed from the Planck satellite and the galaxies of thephotometric redshift catalogue based on the combination of the South GalacticCap u-band Sky Survey (SCUSS), Sloan Digital Sky Survey (SDSS), and Wide-fieldInfrared Survey Explorer (WISE) data. We perform the analyses considering sixredshift bins spanning the range of $0.1 <z<0.7$. From the estimates of thegalaxy-galaxy and galaxy-CMB lensing power spectrum, we derive the galaxy biasand the amplitude of the cross-correlation for each redshift bin. We havefinally applied these tomographic measurements to estimate the linear structuregrowth using the bias-independent $\hat{D}_{G}$ estimator introduced byGiannantonio et al. 2016. We find that the amplitude of the structure growthwith respect to the fiducial cosmology is $A_{D}=1.16\pm 0.13$, closelyconsistent with the predictions of the $\Lambda$CDM model ($A_{D}^{\LambdaCDM}=1$). We perform several tests for consistency of our results, finding nosignificant evidence for systematic effects.
