Nitrous oxide (N 2 O) is an important atmospheric trace gas. The increase in the concentration of N 2 O in the atmosphere has evoked considerable interest because of its role in (i) destroying the ozone layer as a result of producing nitric oxide in the stratosphere, and (ii) ...
Rising concentrations of nitrous oxide (N2O) in the atmosphere are causing widespread concern because this trace gas plays a key role in the destruction of stratospheric ozone and it is a strong greenhouse gas. The successful mitigation of N2O emissions requires a solid understanding of the relative...
Nitrous oxide (N2O), like carbon dioxide, is a long-lived greenhouse gas that accumulates in the atmosphere. Over the past 150 years, increasing atmospheric N2O concentrations have contributed to stratospheric ozone depletion1 and climate change2, with the current rate of increase estimated at 2 ...
Nitrous oxide (N2O), like carbon dioxide, is a long-lived greenhouse gas that accumulates in the atmosphere. Over the past 150 years, increasing atmospheric N2O concentrations have contributed to stratospheric ozone depletion and climate change, with the current rate of increase estimated at 2 per...
As human impacts on the global nitrogen cycle grew rapidly from the industrial revolution onwards, human-induced nitrous oxide emissions also increased. Today, so-called ‘natural sources’ still account for 60 per cent of worldwide emissions each year,
The article discusses the sources as well as the nature of processes involved in dispatching methane from the atmosphere. Greenhouse effect is an important natural phenomenon caused by the presence of methane gas in the atmosphere. The National Institute of Water and Atmospheric Research scientists hav...
A range of environmental factors affect forests’ greenhouse gas emissions In the recently published study, comprehensive measurements of environmental factors in the atmosphere, soil, and trees were combined with nitrous oxide emissions for the first time. The SMEAR II / ICOS research station at the...
The continuous increase of nitrous oxide (N2O) abundance in the atmosphere is a global concern. Multiple pathways of N2O production occur in soil, but their significance and dependence on oxygen (O-2) availability and nitrogen (N) fertilizer source are poorly understood. We examined N2O and nitr...
in the atmosphere through a chemical reaction among air components.Serios air pollution usually results over a city or other area that is emitting high levels of pollutants during a period of air stagnation.The geographic location of some heavily populated cities,such as Los Angelles and Mexico ...
sources of trace metals in the atmosphere are wind-borne soil particles, volcanoes, seasalt spray and wild forest fires2–6. Recent studies have shown, however, that particulate organic matter is the dominant component of atmospheric aerosols in non-urban areas7–10and that over 60% of the ...
