The present data consists in a database of isotope (δO18, δD and deuterium excess) data from precipitations, snow and firn/ice cores, gathering the following data:- the isotopic surface snow data from Masson et al. (2008, doi:10.1175/2007JCLI2139.1)- the Antarctica2k database from Stenni et al. (2017, doi:10.5194/cp-13-1609-2017), available on https://www.ncdc.noaa.gov/paleo-search/study/22589- the data from Fernandoy et al. (2012, doi:10.5194/tc-6-313-2012)- the precipitation data from Rozanski et al. (1993, doi:10.1029/GM078p0001) and available on the IAEA/GNIP platform-data personnally communicatedSee below for full references of articles and datasets.The "averages" xls file give necessary informations to retrieve the data a its original temperoral scale, as well as time-averaged, standard deviations and extremum values. They are completed isotope time-averages and standard deviations from the ECHAM5-wiso model forced to the ERA-interim reanalysis and run at the daily scale over the period 1979-2013 (Werner et al., 2011; doi:10.1029/2011JD015681).The "seasonal_snowfall.xls" file give the seasonal cycles of precipitation, temperature, δO18 and deuterium excecss of snowfall data, as used in the associated manuscript.
