Existing descriptions of bi-directional ammonia (NH3) land-atmosphere exchange incorporate temperature and moisture controls, are beginning to be used in regional chemical transport models. However, such models have typically applied simpler emission factors upscale the main NH3 terms. While this approach has successfully simulated spatial patterns on local global scales, it fails address environment- climate-dependence emissions. To handle these issues, we outline basis for a new modelling...
Livestock production systems currently occupy around 28% of the land surface European Union (equivalent to 65% agricultural land). In conjunction with other human activities, livestock affect water, air and soil quality, global climate biodiversity, altering biogeochemical cycles nitrogen, phosphorus carbon. Here, we quantify contribution these major impacts. For each environmental effect, is expressed as shares emitted compounds used, compared whole sector. The results show that sector...
Abstract. During the last twenty-five years European emission data have been compiled and reported under Cooperative Programme for Monitoring Evaluation of Long-range Transmission Air Pollutants in Europe (EMEP) as part work UNECE Convention on Transboundary Pollution (LRTAP). This paper presents trends SO2 to EMEP validated within programme period 1980–2004. These anthropogenic sulphur emissions steadily decreasing over years, amounting from about 55 Tg 1980 15 2004. The uncertainty...
Adverse health effects from exposure to air pollution are a global challenge and of widespread concern. Recent high ambient concentration episodes pollutants in European cities highlighted the dynamic nature human gaps data knowledge about patterns. In order support impact assessment it is essential develop better understanding individual pathways people's everyday lives by taking account all environments which people spend time. Here we describe development, validation results an method...
China is a global hotspot of atmospheric ammonia (NH3) emissions and, as consequence, very high nitrogen (N) deposition levels are documented. However, previous estimates total NH3 in were much lower than inference from observed values would suggest, highlighting the need for further investigation. Here, we reevaluated based on mass balance approach, validated by N monitoring and satellite observations, period 2000 to 2015. Total increased 12.1 ± 0.8 Tg yr–1 15.6 0.9 2015 at an annual rate...
Abstract Halving nitrogen pollution is crucial for achieving Sustainable Development Goals (SDGs). However, how to reduce from multiple sources remains challenging. Here we show that reactive (Nr) could be roughly halved by managed urban development in China 2050, with NH 3 , NO x and N 2 O atmospheric emissions declining 44%, 30% 33%, respectively, Nr water bodies 53%. While rural-urban migration increases point-source metropolitan areas, it promotes large-scale farming, reducing rural...
Abstract. European emission trends of nitrogen oxides since 1880 and up to present are presented here linked the evolution road transport emissions. Road has been dominating source NOx emissions 1970, contributes with 40% total in 2005. Five trend regimes have identified between The first regime (1880–1950) is determined by a slow increase fuel consumption all over Europe. second (1950–1980) characterized continued steep upward liquid use introduction regulations on traffic Reduction...
Abstract. Excess reactive Nitrogen (Nr) has become one of the most pressing environmental problems leading to air pollution, acidification and eutrophication ecosystems, biodiversity impacts, leaching nitrates into groundwater global warming. This paper investigates how current inventories cover emissions Nr atmosphere in Europe, United States America, China. The focus is on anthropogenic sources, assessing state-of-the-art quantifying Ammonia (NH3), Oxides (NOx) Nitrous Oxide (N2O),...
Abstract. The EMEP4UK modelling system is a high resolution (5×5 km2) application of the EMEP chemistry-transport model, designed for scientific and policy studies in UK. We demonstrate use performance through study ground-level ozone (O3) during extreme August 2003 heat-wave. Meteorology generated by Weather Research Forecast (WRF) nudged every six hours with reanalysis data. focus on SE England, where hourly average O3 reached up to 140 ppb accurately reproduces elevated much its...
Abstract In a recent study, Magnani et al. report how atmospheric nitrogen deposition drives stand‐lifetime net ecosystem productivity (NEP av ) for midlatitude forests, with an extremely high C to N response (725 kg −1 wet‐deposited their European sites). We present here re‐analysis of these data, which suggests much smaller : total inputs. Accounting dry, as well wet reduces the 177 1. However, if covariance intersite climatological differences is accounted for, actual in this dataset may...
