  • Practical use of the ISCST3 model to select monitoring site locations for air pollution control

    We present an objective methodology for selection of the minimum number of sampling sites required to register the highest concentration values of air pollutants emitted from a continuous point source. The methodology is based on the analysis of 1-hour concentration values above a threshold value estimated by atmospheric dispersion models. The number and location of the air monitoring stations ...

  • Multiple sensor fault detection and isolation of an air quality monitoring network using RBF-NLPCA model

    This paper presents a data-driven method based on non-linear principal component analysis to detect and isolate multiple sensor faults. The RBF-NLPCA model is obtained by combining a principal curve algorithm and two three-layer radial basis function (RBF) networks. The reconstruction approach for multiple sensors is proposed in the non-linear case and successfully applied for multiple sensor ...

  • An ambient air quality monitoring network for Buenos Aires city

    This paper proposes an objective methodology for designing a multi-pollutant urban air-quality monitoring network to detect concentrations greater than reference concentration levels (CL). The network design includes both air quality simulation and an objective analysis based on monitoring tasks. The proposed methodology is applied to the city of Buenos Aires. Pollutants of concern are nitrogen ...

  • Estimation of number of deaths associated with exposure to excess ambient PM10 air pollution

    The respirable particle matter (PM10) concentration in urban areas has been a chronic cause concern and principal reason for increased morbidity rate among resident population. The present study aimed at estimating a discrete event like mortality rate associated and attributable to excess particulate matter pollution in the Kathmandu Valley area. The Government of Nepal conducts air monitoring of ...

  • PRESAXIO regional air quality modelling system: validation and applications

    Different operational air quality forecasts (ESSEM Cost Action 0602) are currently available in Europe. However, most of them are not suitable for regional application and, also, their coarse outputs do not fit well with air quality management needs. In this work, PRESAXIO regional air quality modelling system is validated and applied over Galicia (NW of Spain), including WRF and CHIMERE models. ...

  • Two impact related air quality indices as tools to assess the daily and long-term air pollution

    The methodology of the recently developed Daily Air Quality Index (DAQx) and Long-term Air Quality Index (LAQx) is explained. Both indices consider air pollutants frequently monitored at long-term stations within official air pollution control networks. Therefore, they enable an assessment of the integral air pollution, which reflects the ambient air consisting of a mixture of air pollutants more ...

  • A GIS based air quality system for the Apulia region, southern Italy

    A GIS based air quality modelling system has been developed in Apulia region in the Southern Italy, to support local authorities in air quality management. Meteorological and dispersion simulations were performed for the year 2005. Predictions have been compared with concentration data from the air quality monitoring network. Results evidence a good correlation between predictions and ...

  • Analysis of an anomalous case of high air pollution concentration in Turin after a foehn event

    A case of unusually high concentrations of some urban air pollutants (CO, NO, SO2) in Turin (Northwestern Italy) is presented. This episode occurred during the late afternoon of 7 November 1995. This day was characterised by a strong northern foehn event in the morning, which followed the passage of a cold front. The analysis has been carried out by means of data derived from the urban and ...

  • Air Quality Monitoring

    Why monitor air quality? Well, to monitor is to know. Everything else is just more or less qualified guesses. International, national and local air quality targets and limits are also tied to monitoring results. What is Air Quality? How is air quality ...

  • IFDM modelling for optimal siting of air quality monitoring stations around five oil refineries

    An IFDM modelling study has been conducted to determine the optimal siting of air quality monitoring stations around five oil refineries. The purpose of this immission monitoring network is specified in environmental legislation. The most appropriate output parameter of the IFDM model for this study is the 98th percentile of the moving 24 h averages, P98,m24h. Modelling for the optimal siting of ...

  • `Air Permitting for a New Coal-Fired Power Plant,` published in Power magazine, November

    Prevention Of Significant Deterioration (PSD) Construction of any new source, including a greenfield power plant, is subject to New Source Review (NSR). If the source is located in an attainment area, it will also trigger Prevention of Significant Deterioration (PSD) permitting, as required by the Clean Air Act (CAA) for major stationary sources of air pollution in attainment areas. A major ...

  • Influence of sea-land breezes on the tempospatial distribution of atmospheric aerosols over coastal region

    The influence of sea-land breezes (SLBs) on the spatial distribution and temporal variation of particulate matter (PM) in the atmosphere was investigated over coastal Taiwan. PM was simultaneously sampled at inland and offshore locations during three intensive sampling periods. The intensive PM sampling protocol was continuously conducted over a 48-hr period. During this time, PM2.5 and ...

  • Investigating weekend air quality observations with the aid of Fourier analysis in Athens, Greece

    Weekend air quality is analysed with the aid of Fourier analysis, in order to reveal time-series structures for Athens, Greece. For this reason, an appropriate analysis of a 10 year record from 1990–1999 of air quality data from the monitoring network in Athens is carried out for two specific monitoring sites. The aim of the paper is to investigate the temporal pattern of observations in order to ...

  • Status of black carbon monitoring in ambient air in Europe

    Black carbon (BC) is increasingly discussed in science and environmental policy areas as an example of an air pollutant that affects both human health and contributes to climate change (e.g. WHO, 2012; UNEP/WMO, 2011; Bond et al., 2013; IPCC, 2013). In order to be able to make comparable measurements of BC in ambient air and to relate BC monitoring to health impacts and climate change it is ...
