Water isotopic composition in ice core records is classically interpreted as a temperature proxy. In fact, the isotopic composition integrates the whole hydrological cycle, leading to a proxy signal recorded by ice cores different the local climatic variations. Here, I will be introducing a holistic, multi-disciplinary approach to the interpretation of the isotopic signal, combining long term observations of vapor, precipitation and surface snow isotopic. Ongoing work will use a wide range of numerical methods to evaluate physically-based estimates of the isotopic paleothermometer, i.e. the slope between isotopes and temperature, or detect the signature of climate change in Antarctica. to conform to the eventual AESA digital data acquisition and control interfaces as AESA and RBE development converge. Together, the simulator and RBE are used to evaluate/validate the radar at the system level.
