Effect of land surface processes on precipitation isotopes

Kei Yoshimura (1)

Precipitation isotopes variability is dominantly controlled by large-scale atmospheric moisture transport processes. However, we cannot neglect some effect of land surface processes on the variability of precipitation isotopes; in particular, the effect on diurnal variations on precipitation seems quite large. To take a deeper insight on short-term variability of precipitation isotopes, including diurnal variability, the authors developed an isotope-incorporated land surface model coupled with the existed atmospheric isotope circulation model. The original land surface model is MATSIRO (Minimal Advanced Treatments of Surface Interaction and Runoff) by Takata et al. (2003). The atmospheric model, we used the Rayleigh-type isotope circulation model (Yoshimura et al., 2003).
