The spread of mineral particles over southwestern, western, and central Europe resulting from a strong Saharan dust outbreak in October 2001 was observed at 10 stations the European Aerosol Research Lidar Network (EARLINET). For first time, an optically dense desert plume characterized coherently with high vertical resolution on continental scale. main layer located above boundary (above 1‐km height sea level (asl)) up to 3–5‐km height, traces reached heights 7–8 km. particle optical depth...
Abstract. This review provides a community's perspective on air quality research focusing mainly developments over the past decade. The article perspectives current and future challenges as well needs for selected key topics. While this paper is not an exhaustive of all areas in field quality, we have topics that feel are important from policy perspectives. After providing short historical overview, focuses improvements characterizing sources emissions pollution, new observations...
An intercomparison of the algorithms used to retrieve aerosol extinction and backscatter starting from Raman lidar signals has been performed by 11 groups scientists involved in European Aerosol Research Lidar Network (EARLINET). This is part an extended quality assurance program on lidars EARLINET. instruments were tested separately. The use synthetic data, simulated at 355, 532, 386, 607 nm, with realistic experimental atmospheric conditions taken into account. demonstrates that...
During the Lindenberg Aerosol Characterization Experiment (LACE 98) simultaneous measurements with ground‐based and airborne lidars two aircraft equipped aerosol in situ instrumentation were performed. From lidar measurements, particle backscatter coefficients at up to eight wavelengths between 320 1064 nm extinction 2–3 292 532 determined. Thus, for first time, an extensive set of optical properties from several platforms was available inversion into microphysical quantities. For this...
An intercomparison of aerosol backscatter lidar algorithms was performed in 2001 within the framework European Aerosol Research Lidar Network to Establish an Climatology (EARLINET). The objective this research test correctness and influence ratio used by various teams involved EARLINET for calculation backscatter-coefficient profiles from signals. exercise consisted processing synthetic signals degrees difficulty. One these contained height-dependent ratios vertical those on retrieval...
Since 2000, regular lidar observations of the vertical aerosol distribution over Europe have been performed within framework EARLINET, European Aerosol Research Lidar Network. A statistical analysis concerning volume light extinction coefficients particles derived from Raman measurements at 10 EARLINET stations is presented here. The profiles were measured on a fixed schedule with up to two per week; they typically covered height range 500 m 6000 above ground level (agl). made for planetary...
In central Europe, ammonium sulphate and nitrate make up a large fraction of fine particles which pose threat to human health. Most studies on air pollution through particulate matter investigate the influence emission reductions sulphur- nitrogen oxides aerosol concentration. Here, we focus ammonia (NH3) emissions. Emission scenarios have been created basis improved parameterization implemented in SMOKE for Europe CMAQ model systems described part I this study. This includes emissions based...
Abstract. The North Sea is one of the areas with highest ship traffic densities worldwide. At any time, about 3000 ships are sailing its waterways. Previous scientific publications have shown that contribute significantly to atmospheric concentrations NOx, particulate matter and ozone. Especially in case ozone, this influence can even be seen regions far away from main shipping routes. In order quantify effects on air quality bordering states, it essential determine emissions as accurately...
Abstract. The Baltic Sea is a highly frequented shipping area with busy lanes close to densely populated regions. Exhaust emissions from ship traffic into the atmosphere do not only enhance air pollution, they also affect environment through acidification and eutrophication of marine waters surrounding terrestrial ecosystems. As part European BONUS project SHEBA (Sustainable Shipping Environment region), transport, chemical transformation fate atmospheric pollutants in region were simulated...
Abstract. Shipping emissions have significant influence on atmospheric environment as well human health, especially in coastal areas and the harbour districts. However, contribution of shipping China still need to be clarified based measurement data, with large number ownership vessels rapid developments ports, international trade shipbuilding industry. Pollutants gaseous phase (carbon monoxide, sulfur dioxide, nitrogen oxides, total volatile organic compounds) particle (particulate matter,...
Abstract. Current understanding of mercury (Hg) behavior in the atmosphere contains significant gaps. Some key characteristics Hg processes, including anthropogenic and geogenic emissions, atmospheric chemistry, air–surface exchange, are still poorly known. This study provides a complex analysis processes governing fate involving both measured data from ground-based sites simulation results chemical transport models. A variety long-term measurements gaseous elemental (GEM) reactive (RM)...
Abstract. The US EPA regional emission model SMOKE was adopted and modified to create temporally spatially distributed for Europe surrounding countries based on official reports public domain data only. aim is develop a flexible capable of creating consistent high resolution long-term runs Chemical Transport Models (CTMs). This version SMOKE, called EUROPE (SMOKE-EU) successfully used hourly gridded emissions the timespan 1970–2010. In this paper SMOKE-EU underlying European datasets are...
Pollutants from fishing boats have generally been neglected worldwide, and there is an acute shortage of measured emission data, especially in China. Therefore, on-board measurements pollutants emitted 12 different China (including gill net, angling, trawler boats) were carried out this study to investigate factors (EFs), characteristics total emissions. The average EFs for CO2, CO, NOx, PM, SO2 3074 ± 55.9, 50.6 31.7, 54.2 30.7, 9.54 2.24, 5.94 6.38 g (kg fuel)−1, respectively, which higher...
Abstract. Air pollution due to shipping is a serious concern for coastal regions in Europe. Shipping emissions of nitrogen oxides (NOx) air over the Baltic Sea are similar magnitude (330 kt yr−1) as combined land-based NOx from Finland and Sweden all emission sectors. Deposition compounds originating activities contribute eutrophication areas region. For North control area (NECA) will become effective 2021; accordance with International Maritime Organization (IMO) target reducing ships....
