  abstract = {{T}he interpretation of the isotopic composition of {A}ndean ice cores (oxygen-18 and deuterium) is still in debate. {I}n 2000, an ice core has been extracted from the {C}himborazo glacier, in {E}cuador, and the isotopic composition has been measured with a seasonal temporal resolution over the last century. {T}o reliably interpret this isotopic record in terms of climate, an isotopic calibration based on modern precipitation is needed. {T}hus, since 2001, an {E}cuadorian network has been set up to monitor the isotopic composition of precipitation. {H}ere, we present the first results from {F}ebruary 2001 to {N}ovember 2002 at the site of the {N}uevo {R}ocafuerte station (74.5 degrees {W}, 0.9 degrees {S}, 250 m). {O}ur study shows that at both daily and seasonal timescales, the local meteorological parameters are very poor factors to explain the isotopic variability. {H}owever, the rainout upstream (intensity of the convection over the {E}cuadorian {A}mazon) can explain up to 70% of the isotopic variability at the seasonal timescale. {T}hus, the isotopic records from the {C}himborazo glacier could offer a record of the past variability of the {E}cuadorian precipitation over the {A}mazon basin.},
