Global and local meteoric water lines for δ¹⁷O/δ¹⁸O and the spatiotemporal distribution of Δ'¹⁷O in Earth's precipitation.

ABSTRACT: Recently, δ¹⁷O and its excess (Δ'¹⁷O) have become increasingly significant "triple-oxygen-isotope" indicators of distinctive hydrological processes in hydrology and climatology. This situation mirrors the research regarding δ¹⁸O and δ²H in the 1960s towards a solid theoretical base and a surge in application examples and field studies worldwide. Currently, systematic global measurements for δ¹⁷O in precipitation are still lacking. As a result, attempts have been made to define a Global δ¹⁷O/δ¹⁸O Meteoric Water Line (GMWL), often by using regional or local datasets of varying systematicity. Different definitions of the global reference slope (λ_ref) for determining Δ'¹⁷O values have been propos
