Abstract
This data set is a new N2O isotopic data set including site preference isotopic data derived from ice core samples containing air spanning the deglacial N2O rise (16.5-13.2 ka). The data extend through the Younger Dryas cooling interval, when N2O decreased by about 30 ppb (13.2-11.9 ka). The data set also contains N2O isotope records spanning the Heinrich Stadial 4 / Dansgaard-Oeschger 8 (HS4/DO8) transition (39.8-35.8 ka), an example of cyclical millennial-scale N2O variability characteristic of the last ice age.
