Unexpectedly minor nitrous oxide emissions from fluvial networks draining permafrost catchments of the East Qinghai-Tibet Plateau

Abstract

Permafrost soils can be substantial sources of nitrous oxide (N2O) to the atmosphere, but no data exist on the N2O footprints of permafrost rivers. Here, the authors show that alpine permafrost rivers are unexpectedly small sources of atmospheric N2O at present.
