This requires an homogeneously analysed sample covering a wide range of ages and distances. In this aper we present the OCCASO second data release. This comprises a sample of high-resolution ($R>65,000$) and high signal-to-noise spectra of 115 Red Clump stars in 18 Open Clusters. We derive atmospheric parameters ($T_{\\mathrm{eff}}$, $\\log g$, $\\xi$), and [Fe/H] abundances using two analysis techniques: equivalent widths and spectral synthesis.
