Abstract. This paper describes the pre-operational analysis and forecasting system developed during MACC (Monitoring Atmospheric Composition Climate) continued in MACC-II Climate: Interim Implementation) European projects to provide air quality services for continent. is based on seven state-of-the art models run Europe (CHIMERE, EMEP, EURAD-IM, LOTOS-EUROS, MATCH, MOCAGE SILAM). These are used calculate multi-model ensemble products. The gives an overall picture of its status at end (summer...
In low potential agricultural areas like the Honduran hillsides characterized by soil degradation and erosion, organic agriculture can provide a means to break downward spiral of resource poverty. We use original survey data analyze factors influencing decision convert agriculture. Previous studies have emphasized role spatial patterns in diffusion adoption technologies general particular. These result from variety underlying factors. this article we test various explanations, including...
Measurements of changes in the atmospheric O2/N2 ratio have typically relied on compressed air derived from highpressure tanks as reference material against which are assessed. The validity this procedure is examined here context history 18 compared over a 12-yr time-frame. By considering differences tank sizes, types, and by performing additional tests, long-term stability delivered gas evaluated with respect to surface reactions, leakage, regulator effects, thermal diffusion gravimetric...
Projections of future surface ozone over Europe conducted utilizing chemistry transport models (CTMs) coupled to climate differ greatly, even in sign. CTM sensitivity studies were order investigate the importance changes natural isoprene emissions and dry deposition vegetation, both meteorology. This knowledge can be used improve projections. Our simulations suggest change would cause between −4.0 +13 ppb(v) on average (April–September) −3.5 +25 daily maximum from 1961–1990 2071–2100. The is...
Ozone is a highly oxidative pollutant formed from precursors in the presence of sunlight, associated with respiratory morbidity and mortality. All else being equal, concentrations ground-level ozone are expected to increase due climate change. Ozone-related health impacts under changing projected using emission scenarios, models epidemiological data. European modelled model atmospheric transport chemistry (MATCH)-RCA3 (50×50 km). Projections two models, ECHAM4 HadCM3, applied greenhouse gas...

The impact of climate and emissions changes on the deposition reactive nitrogen (Nr) over Europe was studied using four offline regional chemistry transport models (CTMs) driven by same global projection future period 2000–2050. Anthropogenic for years 2005 2050 were used simulations both present periods in order to isolate change, hemispheric boundary conditions emissions, assess robustness results across different models. from these CTMs clearly show that main driver N-deposition...
Abstract. The wet deposition of nitrogen and sulfur in Europe for the period 1990–2010 was estimated by six atmospheric chemistry transport models (CHIMERE, CMAQ, EMEP MSC-W, LOTOS-EUROS, MATCH MINNI) within framework EURODELTA-Trends model intercomparison. simulated its trends two 11-year periods (1990–2000 2000–2010) were evaluated using data from observations European monitoring network. For annual oxidised (WNOx), bias 30 % average most models. There a tendency to underestimate reduced...
Abstract. Residential wood combustion (RWC) is an important contributor to air quality in numerous regions worldwide. This study the first extensive evaluation of influence RWC on ambient several Nordic cities. We have analysed emissions and concentrations PM2.5 cities within four countries: metropolitan areas Copenhagen, Oslo, Helsinki city Umeå. evaluated for relevant urban source categories modelled atmospheric dispersion regional scales. The emission inventories were based local surveys,...
Earth system and environmental impact studies need high quality up-to-date estimates of atmospheric deposition. This study demonstrates the methodological benefits multimodel ensemble measurement-model fusion mapping approaches for deposition focusing on 2010, a year which several were conducted. Global model-only assessment can be further improved by integrating new model-measurement techniques, including expanded capabilities satellite observations composition. We identify research...

Air pollution is an important environmental factor associated with health impacts in Europe and considerable resources are used to reduce exposure air through emission reductions. These reductions will have non-linear effects on due, e.g., interactions between climate atmospheric chemistry. By using integrated assessment model, we quantify the effect of changes climate, emissions population demography Europe.

Ozone air pollution is identified as one of the main threats bearing upon human health and ecosystems, with 25 000 deaths in 2005 attributed to surface ozone Europe (IIASA 2013 TSAP Report #10). In addition, there a concern that climate change could negate mitigation strategies, making them insufficient over long run jeopardising chances meet term objective set by European Union Directive 2008 (Directive 2008/50/EC Parliament Council 21 May 2008) (60 ppbv, daily maximum). This effect has...
