This file includes model outputs to help with the analysis of associated the vapour isotopic composition. The data was produced from the MAR model following the locations of the traverse to study the variations of isotopic composition with the local climatic parameters in extremely remote and dry regions of Antarctica in order to understand better the isotopic paleothermometer in the framework of Casado et al, [manuscript under review].121.64268139.83335-80.7996-66.69946
