Nitrous oxide (N2O) is an important greenhouse gas which destroys the ozone in the stratosphere. Primary sources of atmospheric N2O are nitrification and denitrification in terrestrial soils and the ocean, and the main sink is photolysis in the stratosphere. Studies have mostly focused on the climate-related response of N2O during glacial-interglacial periods. However, its mechanism of variation during the Holocene remains unclear. We present a high-resolution N2O record from the South Pole Ice (SPICE) core covering the Holocene epoch.
