Using the almost all-sky 2MASS Photometric Redshift catalogue (2MPZ) weperform for the first time a tomographic analysis of galaxy angular clusteringin the local Universe ($z<0.24$). We estimate the angular auto- and cross-powerspectra of 2MPZ galaxies in three photometric redshift bins, and use dedicatedmock catalogues to assess their errors. We measure a subset of cosmologicalparameters, having fixed the others at their Planck values, namely the baryonfraction $f_{b}=0.14^{+0.09}_{-0.06}$, the total matter density parameter$\Omega_{\rm m}=0.30\pm 0.06$, and the effective linear bias of 2MPZ galaxies$b_{\rm eff}$, which grows from $1.1^{+0.3}_{-0.4}$ at $\langle z \rangle=0.05$up to $2.1^{+0.3}_{-0.5}$ at $\langle z\rangle=0.2$, largely because of theflux-limited nature of the dataset. The results obtained here for the localUniverse agree with those derived with the same methodology at higherredshifts, and confirm the importance of the tomographic technique fornext-generation photometric surveys such as Euclid or LSST.
