Context : The AMBRE Project is a collaboration between the European Southern Observatory ( ESO ) and the Observatoire de la Côte d ’ Azur ( OCA ) that has been established in order to carry out the determination of stellar atmospheric parameters for the archived spectra of four ESO spectrographs .

Aims : The analysis of the UVES archived spectra for their stellar parameters has been completed in the third phase of the AMBRE Project .
From the complete ESO : UVES archive dataset that was received covering the period 2000 to 2010 , 51921 spectra for the six standard setups were analysed .
These correspond to approximately 8014 distinct targets ( that comprise stellar and non-stellar objects ) by radial coordinate search .

Methods : The AMBRE analysis pipeline integrates spectral normalisation , cleaning and radial velocity correction procedures in order that the UVES spectra can be then analysed automatically with the stellar parameterisation algorithm MATISSE to obtain the stellar atmospheric parameters .
The synthetic grid against which the MATISSE analysis is carried out is currently constrained to parameters of FGKM stars only .

Results : Stellar atmospheric parameters are reported for 12,403 of the 51,921 UVES archived spectra analysed in AMBRE : UVES .
This equates to \sim 23.9 % of the sample and \sim 3,708 stars .
Effective temperature , surface gravity , metallicity and alpha element to iron ratio abundances are provided for 10,212 spectra ( \sim 19.7 % ) , while at least effective temperature is provided for the remaining 2,191 spectra .
Radial velocities are reported for 36,881 ( \sim 71.0 % ) of the analysed archive spectra .
Typical external errors of \sigma _ { T _ { \textrm { eff } } } \sim 110 dex , \sigma _ { \log g } \sim 0.18 dex , \sigma _ { \textrm { [ M / H ] } } \sim 0.13 dex , and \sigma _ { [ \alpha / \textrm { Fe } ] } \sim 0.05 dex with some reported variation between giants and dwarfs and between setups are reported .

Conclusions : UVES is used to observe an extensive collection of stellar and non-stellar objects all of which have been included in the archived dataset provided to OCA by ESO .
The AMBRE analysis extracts those objects which lie within the FGKM parameter space of the AMBRE slow rotating synthetic spectra grid .
Thus by homogeneous blind analysis AMBRE has successfully extracted and parameterised the targeted FGK stars ( 23.9 % of the analysed sample ) from within the ESO : UVES archive .
