Interannual variability in the oxygen isotopes of atmospheric CO2 driven by El Niño
LR Welp, RF Keeling, HAJ Meijer, AF Bollenbacher… - Nature, 2011 - nature.com
The stable isotope ratios of atmospheric CO 2 ( 18 O/ 16 O and 13 C/ 12 C) have been
monitored since 1977 to improve our understanding of the global carbon cycle, because …

Atmospheric evidence for a global secular increase in carbon isotopic discrimination of land photosynthesis
A decrease in the 13 C/ 12 C ratio of atmospheric CO 2 has been documented by direct
observations since 1978 and from ice core measurements since the industrial revolution. This …

A meta‐analysis of water vapor deuterium‐excess in the midlatitude atmospheric surface layer
Deuterium‐excess (d) in water is a combination of the oxygen (δ 18 O) and hydrogen (δD)
isotope ratios, and its variability is thought to indicate the location and environmental …
