The AMBRE collaboration between the Observatoire de la Côte d'Azur (OCA, Nice) and ESO has the goal to analyse the wealth of stellar spectroscopic data in the ESO science archive using the MATISSE parametrisation algorithm to derive stellar atmospheric parameters (Recio-Blanco et al., 2006, Worley et al. 2012, de Laverny et al. 2012, De Pascale et al. 2014. This data release provides stellar radial velocity, effective temperature, surface gravity, mean metallicity and enrichment in alpha-elements for about 4480 distinct stellar objects observed between October 2003 and October 2010 using HARPS (378 nm – 691 nm).
