A model of nitrous oxide evolution from soil driven by rainfall events: 1. Model structure and sensitivity [PDF]

, 1992
This paper describes a rain-event driven, process-oriented simulation model, DNDC, for the evolution of nitrous oxide (N2O), carbon dioxide (CO2), and dinitrogen (N2) from agricultural soils.

Characteristics and Influencing Factors of Soil CH4 and N2O Fluxes in Typical Broad-leaved Forests in the Yangtze River Delta Region, China

Shuitu Baochi Xuebao
[Objective] The forest coverage rate in the Yangtze River Delta region reaches 33.4%, and the underlying surface soil may have an important impact on the regional greenhouse gas budget.

Spatial variability of nitrous oxide in the Minho and Lima estuaries (Portugal)

Scientia Marina, 2017
Nitrous oxide (N2O) is a potent long-lived greenhouse gas and estuaries represent potentially important sources of this biogas to the atmosphere. In this work, we analyse the first N2O data obtained in the Minho and Lima estuaries, and the processes and ...

Nitrous oxide and methane in the Atlantic Ocean between 50 degrees North and 52 degrees South: Latitudinal distribution and sea-to-air flux [PDF]

, 2008
We discuss nitrous oxide (N2O) and methane (CH4) distributions in 49 vertical profiles covering the upper 300 m of the water column along two 13,500 km transects between 50°N and 52°S during the Atlantic Meridional Transect (AMT) programme (AMT cruises ...

Nitrous Oxide Emissions from Smallholders’ Cropping Systems in Sub-Saharan Africa

Advances in Agriculture, 2021
Increased concentration of atmospheric nitrous oxide (N2O), a potent greenhouse gas (GHG), is of great concern due to its impact on ozone layer depletion leading to climate change. Ozone layer depletion allows penetration of ultraviolet radiations, which

Marine N2O cycling from high spatial resolution concentration, stable isotopic and isotopomer measurements along a meridional transect in the eastern Pacific Ocean

Frontiers in Marine Science, 2023
Nitrous oxide (N2O) is a potent greenhouse gas and ozone depleting substance, with the ocean accounting for about one third of global emissions. In marine environments, a significant amount of N2O is produced by biological processes in Oxygen Deficient ...

Distributions, sources, and air-sea fluxes of nitrous oxide in Bohai Bay, China

Frontiers in Marine Science, 2023
IntroductionPolluted bays are one of the critical areas for the production and emissions of marine nitrous oxide (N2O), which has a strong effect on global warming and plays a critical role in stratospheric ozone depletion.MethodsIn 2020, the ...

The effect of cattle slurry in combination with nitrate and the nitrification inhibitor dicyandiamide on in situ nitrous oxide and dinitrogen emissions [PDF]

, 2012
peer-reviewedA field study was conducted to determine the effect of the nitrification inhibitor dicyandiamide (DCD) on N2O and N2 emissions after cattle slurry (CS) application in the presence of nitrate (NO3) fertiliser on seven different occasions ...

The Optimization of Hypobromite Oxidation Combined with Sodium Azide Chemical Methods and Determination of the Nitrogen Isotopic Composition of Dissolved Ammonium in Seawater

Journal of Isotopes
Ammonium is a key dissolved inorganic nitrogen (DIN) in the biogeochemical cycle of nitrogen in the ocean. Depending on the environment，the 15N natural abundance (δ15Nair ) of NH4+ can provide insights into N sources and mechanisms of N transformations ...

Inland Waters can Act as Nitrous Oxide Sinks: Observation and Modeling Reveal that Nitrous Oxide Undersaturation May Partially Offset Emissions

Geophysical Research Letters, 2023
Inland waters are significant, yet highly uncertain, natural sources of nitrous oxide (N2O). Many emission models assume that N2O is only emitted from freshwaters, and that N2O sink behavior is negligible. However, observational studies have reported N2O
