  In a tomographic approach, we measure the cross-correlation between the CMB
lensing reconstructed from the Planck satellite and the galaxies of the
photometric redshift catalogue based on the combination of the South Galactic
Cap u-band Sky Survey (SCUSS), Sloan Digital Sky Survey (SDSS), and Wide-field
Infrared Survey Explorer (WISE) data. We perform the analyses considering six
redshift bins spanning the range of $0.1 <z<0.7$. From the estimates of the
galaxy-galaxy and galaxy-CMB lensing power spectrum, we derive the galaxy bias
and the amplitude of the cross-correlation for each redshift bin. We have
finally applied these tomographic measurements to estimate the linear structure
growth using the bias-independent $\hat{D}_{G}$ estimator introduced by
Giannantonio et al. 2016. We find that the amplitude of the structure growth
with respect to the fiducial cosmology is $A_{D}=1.16\pm 0.13$, closely
consistent with the predictions of the $\Lambda$CDM model ($A_{D}^{\Lambda
CDM}=1$). We perform several tests for consistency of our results, finding no
significant evidence for systematic effects.
