What controls deuterium excess in global precipitation? [PDF]
Climate of the Past, 2014 The deuterium excess (d) of precipitation is widely used in the reconstruction of past climatic changes from ice cores. However, its most common interpretation as moisture source temperature cannot directly be inferred from present-day ...

Controls on Deuterium Excess across Asia
Geosciences, 2018 Deuterium excess (d-excess) is a second-order stable isotope parameter measured in meteoric water to understand both the source of precipitation and the evolution of moisture during transport.

The Seasonality of Deuterium Excess in Non‐Polar Precipitation
Global Biogeochemical Cycles, 2022 AbstractThe deuterium excess (d‐excess) of precipitation varies seasonally at sites across the globe, an observation that has often been linked to seasonal changes in oceanic evaporation conditions, continental moisture recycling, and subcloud raindrop re‐evaporation.

Comparing deuterium excess to large-scale precipitation recycling models in the tropics [PDF]
npj Climate and Atmospheric Science, 2021 Precipitation recycling is essential to sustaining regional ecosystems and water supplies, and it is impacted by land development and climate change.

Geophysical Research Letters, 2023 The deuterium excess (d‐excess) and more recently developed 17O excess (Δ′17O) of precipitation are isotopic tracers that are sensitive to oceanic moisture source (OMS) conditions.

Deuterium excess and 17O-excess variability in meteoric water across the Pacific Northwest, USA
Tellus: Series B, Chemical and Physical Meteorology, 2020 High-precision triple oxygen isotope analysis of water has given rise to a novel second-order parameter, 17O-excess (often denoted as Δ17O), which describes the deviation from a reference relationship between δ18O and δ17O.

Deuterium excess as a proxy for continental moisture recycling and plant transpiration [PDF]
Atmospheric Chemistry and Physics, 2014 Studying the evaporation process and its link to the atmospheric circulation is central for a better understanding of the feedbacks between the surface water components and the atmosphere.

A Dataset of Water Stable Isotopes in Iran’s Main Aquifers [PDF]
Scientific DataAlthough the number of global water stable isotope databases (δ18O and δ2H) is growing, accessible groundwater stable isotope data on developing countries (e.g., Iran), are conspicuously lacking.

The Impact of Nonequilibrium and Equilibrium Fractionation on Two Different Deuterium Excess Definitions [PDF]
Journal of Geophysical Research D: Atmospheres, 2017 AbstractThe deuterium excess (d) is a useful measure for nonequilibrium effects of isotopic fractionation and can therefore provide information about the meteorological conditions in evaporation regions or during ice cloud formation. In addition to nonequilibrium fractionation, two other effects can change d during phase transitions.
