temperature could probably be taken as a surrogate of this relationship at sites
such as Vostok and EPICA Dome C (estimates within 10% to þ 30%).
Jouzel et al. (1997) developed a simple model that dealt with isotopic
fractionation in an isolated air parcel traveling from an oceanic source toward a
polar region. In this simple model, the condensed phase is assumed to form in
isotopic equilibrium with the surrounding vapor and to be removed immediately
