TLDR
In this paper, the ozone depletion potential-weighted anthropogenic emissions of N2O with those of other ozone-depleting substances were compared, and it was shown that N 2O emission currently is the single most important ozone-destroying emission and is expected to remain the largest throughout the 21st century.Abstract:
By comparing the ozone depletion potential-weighted anthropogenic emissions of N2O with those of other ozone-depleting substances, we show that N2O emission currently is the single most important ozone-depleting emission and is expected to remain the largest throughout the 21st century. N2O is unregulated by the Montreal Protocol. Limiting future N2O emissions would enhance the recovery of the ozone layer from its depleted state and would also reduce the anthropogenic forcing of the climate system, representing a win-win for both ozone and climate.read more

TL;DR: Although N2O was produced mainly via NH2OH oxidation pathway in the autotrophic partial nitrification reactor,N2O production mechanisms were complex and could involve multiple N2o production pathways.

Formation of N2O greenhouse gas during SCR of NO with NH3 by supported vanadium oxide catalysts
TL;DR: In this article, a series of temperature-programmed surface reaction studies with isotopic labelled reactants was performed to elucidate the fundamental aspects of the N2O formation reaction and to guide the rational design of improved SCR catalysts for diesel engines with reduced NO produced.

TL;DR: In this paper, atmospheric measurements of atmospheric N2O spanning altitudes from the surface to 14 km, and latitudes from 67°S to 85°N, show high concentrations in the tropics and subtropics, with strong maxima in the middle and upper troposphere.

TL;DR: In this paper, a time-dependent Bayesian inversion technique was used to estimate the global N2O surface fluxes for 11 years from 1999 to 2009 using observations from 5 different networks, incorporating 59 surface sites and a number of ship-based measurement series.
