Evolution of 18O and D enrichment factors a as a function of RH (in %) for 2 months of exposure and b as a function of time at 90% RH (0, 0.03, 2, and 14 months). Values presented in (a, b) come from S1 series. Errors are given at the 1σ confidence interval; if not visible, they are smaller than the symbols
