Abstract. A novel method for estimating the mixing height based on ceilometer measurements is described and tested against commonly used methods determining height. In this an idealised backscatter profile fitted to observed profile. The one of parameters. An extensive amount data vertical soundings from Helsinki area in 2002 utilized test applicability determination. results, including 71 convective 38 stable cases, show that clear sky conditions heights determined aerosol profiles...
Abstract. Urban air pollution is associated with significant adverse health effects. Model-based abatement strategies are required and developed for the growing urban populations. In initial development stage, these focussed on exceedances of quality standards caused by high short-term pollutant concentrations. Prediction effects implementation information systems require accurate forecasting episodes population exposure, including modelling emissions, meteorology, atmospheric dispersion...
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,...
Health effect estimates depend on the methods of evaluating exposures. Due to non-linearities in exposure-response relationships, both predicted mean exposures as well its spatial variability are significant. The aim this work is systematically quantify impact resolution population-weighted concentration (PWC), variance, and mortality attributable fine particulate matter (PM2.5) exposure Finland 2015. atmospheric chemical transport model SILAM was used estimate ambient air PM2.5...
Abstract A new three-step idealized-profile method to estimate the mixing height from vertical profiles of ceilometer backscattering coefficient is developed address weaknesses found with such estimates that are based on one-step method. This fits profile measurements into an idealized scaled three error functions, thus having potential determine aerosol layers (one for surface layer, one height, and artificial layer caused by weakened signal). tested radiosounding data collected during...
Abstract. A mathematical model is presented for the determination of human exposure to ambient air pollution in an urban area; a refined version previously developed EXPAND (EXposure Particulate matter And Nitrogen oxiDes). The combines predicted concentrations, information on people's activities and location population evaluate spatial temporal variation average different microenvironments. revisions modelling system containing include improvements associated emission dispersion system,...
Abstract. We present an overview of the modelling particle number concentrations (PNCs) in five major European cities, namely Helsinki, Oslo, London, Rotterdam, and Athens, 2008. Novel emission inventories numbers have been compiled both on urban scales. used atmospheric dispersion for PNCs target cities a scale, evaluated predicted results against available measured concentrations. In all (PNs) were mostly influenced by emissions originating from local vehicular traffic. The influence...
Abstract. Even though emission inventories indicate that wood combustion is a major source of polycyclic aromatic hydrocarbons (PAHs), estimating its impacts on PAH concentration in ambient air remains challenging. In this study the effect local small-scale benzo[a]pyrene (BaP) concentrations Helsinki metropolitan area Finland evaluated, using measurements, estimates, and dispersion modeling. The measurements were conducted at 12 different locations during period from 2007 to 2015. spatial...
Air pollution has been estimated to be one of the leading environmental health risks in Finland. National impact estimates existing date have focused on particles (PM) and ozone (O₃). In this work, we quantify impacts particles, ozone, nitrogen dioxide (NO₂) 2015, analyze related uncertainties. The exposures were with a high spatial resolution chemical transport model, adjusted observed concentrations. We calculated according Word Health Organization (WHO) working group recommendations....
An operational urban air quality modelling system ENFUSER is presented with an evaluation against measured data. combines several dispersion approaches, uses data assimilation, and continuously extracts information from online, global open-access sources. The area described a combination of geographic datasets. These GIS datasets are globally available open access, therefore the model can be applied worldwide. Urban scale addressed Gaussian puff plume modelling, long-range transport...
Primary biological aerosols in the Earth atmosphere, including pollen, fungal spores, bacteria and viruses, constitute a substantial fraction of are actively dispersed by winds over large distances. The composition bioaerosols is determined vegetation at surface influenced seasonal shifts, weather patterns, can be modulated air pollution levels.   Aerial microbes, which make up less than 1% airborne entities, have often been overlooked due to challenges traditional monitoring...
