Researchers from the University of Maryland tracked lightning storms in real-time using NASA's TEMPO instrument, detecting nitrogen oxide emissions that affect climate and air quality. The study reveals how lightning can produce pollutants that travel long distances, influencing air quality far from the original storm.
A new study reveals China's NTEs were significant sources of CH₄ and N₂O emissions between 1980 and 2020, with an accumulated GWP of 5.55 Pg CO₂-equivalent. The net warming effect is primarily driven by N₂O emissions.
A new study published in Nature Ecology & Evolution found that warmer temperatures and nitrogen fertilization can stabilize soil carbon levels, contradicting earlier predictions. Plant roots and growth add new carbon to the soil, counteracting the loss of carbon due to climate change.
Researchers found that nitrogen emissions from human activities cool the climate by minus 0.34 watts per square metre, but also cause harm to health, biodiversity, and the ozone layer. The study warns against increasing atmospheric nitrogen as a means of combating global warming.
A new study by RIKEN CSRS shows that biomass from purple photosynthetic marine bacterium Rhodovulum sulfidophilum is an excellent nitrogen fertilizer, effective as inorganic synthetic fertilizers but with lower environmental side effects. The biomass boosts plant growth without altering soil pH or salinity.
Researchers from Tampere University discovered that marine organisms can form new atmospheric particles in the South Pacific Ocean, which could help explain climate change predictions. The study found that these particles were formed at night and were accompanied by signs of nitrogenous compounds.
Researchers found that high nitrogen monoxide emissions in cities lead to overestimation of ground-level ozone concentrations by up to 50 percent. The Leighton ratio, used in computer models, is flawed when nitrogen monoxide levels are high.
Research reveals that tropospheric ozone contributes more to the Southern Ocean's warming than previously thought. This finding highlights the importance of reducing air pollution to mitigate ocean heat uptake and climate change.
Researchers found that exposure to six major air pollutants remains higher for racial and ethnic minorities than white Americans, regardless of income level. The study used models incorporating data from satellites and EPA monitoring stations to map pollution levels onto census demographic groups across the contiguous US.
Researchers found that vehicles accounted for 60-84% of total NH3 emissions in western Los Angeles, significantly higher than government estimates. This discovery suggests a substantial health impact from vehicle-related ammonia, which has been largely under-recognized and uncontrolled.
Researchers at Yale University have developed a method to combine atmospheric nitrogen with benzene to produce aniline, a precursor to various synthetic materials. This breakthrough could lead to the creation of new products such as dyes and pharmaceuticals.
Recent research suggests that anthropogenic nitrogen inputs to the North Atlantic may be lower than previously thought. Coral skeletons show minimal changes in nitrogen isotope ratio over the past 130 years, contradicting model simulations predicting a significant decline.
A US study has found that nearly one-quarter of sites across the US are threatened by high levels of atmospheric nitrogen pollution, leading to a loss of plant species richness. The research highlights the vulnerability of grassland ecosystems to nitrogen pollution, particularly those with acidic soil.
