  abstract = {{A} 181.8 m ice core was recovered from a borehole drilled into bedrock on the western plateau of {M}t {E}l'brus (43 degrees 20'53.9 ' {N}, 42 degrees 25'36.0 ' {E}; 5115m a.s.l.) in the {C}aucasus, {R}ussia, in 2009 ({M}ikhalenko et al., 2015). {H}ere, we report on the results of the water stable isotope composition from this ice core with additional data from the shallow cores. {T}he distinct seasonal cycle of the isotopic composition allows dating by annual layer counting. {D}ating has been performed for the upper 126 m of the deep core combined with 20 m from the shallow cores. {T}he whole record covers 100 years, from 2013 back to 1914. {D}ue to the high accumulation rate (1380 mm w.e. year(-1)) and limited melting, we obtained isotopic composition and accumulation rate records with seasonal resolution. {T}hese values were compared with available meteorological data from 13 weather stations in the region and also with atmosphere circulation indices, back-trajectory calculations, and {G}lobal {N}etwork of {I}sotopes in {P}recipitation ({GNIP}) data in order to decipher the drivers of accumulation and ice core isotopic composition in the {C}aucasus region. {I}n the warm season ({M}ay-{O}ctober) the isotopic composition depends on local temperatures, but the correlation is not persistent over time, while in the cold season ({N}ovember-{A}pril), atmospheric circulation is the predominant driver of the ice core's isotopic composition. {T}he snow accumulation rate correlates well with the precipitation rate in the region all year round, which made it possible to reconstruct and expand the precipitation record at the {C}aucasus highlands from 1914 until 1966, when reliable meteorological observations of precipitation at high elevation began.},
