The Need to Clearly State the Reference Temperature and Pressure Conditions when Reporting Gas Volumes or Volumetric Flow Rates

In the physical sciences, such as chemistry, the standard temperature and pressure (STP) is a set of conditions for experimental measurements that enables true comparisons between sets of da-ta representing gas volumes. There are many different definitions of standard temperatures and pressures applicable to gas volumes and volumetric flow rates. The differences depend on the organization ...

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 ...

Meteorological normalisation and non-parametric smoothing for quality assessment and trend analysis of tropospheric ozone data

Despite extensive efforts to ensure that sampling and installation and maintenance of instruments are as efficient as possible when monitoring air pollution data, there is still an indisputable need for statistical post processing (quality assessment). We examined data on tropospheric ozone and found that meteorological normalisation can reveal (i) errors that have not been eliminated by ...

Application of atmospheric dispersion models to evaluate population exposure to NO<SUB><SMALL>2</SMALL></SUB> concentration in Buenos Aires

Application of atmospheric dispersion models to evaluate population exposure to NO₂ concentration in Buenos Aires

Chronic or repeated exposure to low concentrations of NO2 may increase the incidence of respiratory infections especially in the most sensitive persons. Air pollution monitoring data obtained in Buenos Aires City reveal that sometimes NO2 Air Quality Guidelines (AQGs) recommended by the World Health Organization (WHO) is exceeded. We estimate hourly background concentrations (Ch) of NOx ...

Developments in ADMS-Airport to take account of near field dispersion and applications to Heathrow Airport

ADMS-Airport is based on the ADMS-Urban system for modelling urban air quality. In the near field it employs a quasi-Gaussian dispersion model and this is nested within a trajectory model. Aircraft sources are treated explicitly as accelerating jets. Application of the model to air quality calculations was conducted for the Model Inter-Comparison (MIC) Study of Project for the Sustainable ...

Mobile air quality monitors: More data for better informed decisions

HIGHLIGHTS Vehicle-based air quality monitoring makes it possible to obtain hyperlocal data. The data collected by our Kunak Air Mobile station is extremely reliable thanks to the special design of the protective housing. The implementation of this solution makes it possible to complement reference monitoring networks, overcoming the spatial limits of stationary equipment. ...

Reporting and exchanging air quality information using e-Reporting

A number of EU legal instruments require EU Member States to monitor and report air quality data. This information is collated, analysed and disseminated by the European Environment Agency (EEA). At present much of the data is reported electronically by countries in data flows required under a specific legal instrument. As a result, reporting on air quality is not always integrated across all ...

Air quality modelling as a supplementary assessment method in the framework of the European Air Quality Directive

According to the European Air Quality (AQ) Directive, member states must annually report their AQ to the European Commission (EC). This report can be based on modelling data if the concentration levels do not exceed the established lower assessment thresholds (LAT), or on combined data from modelling and monitoring systems (supplementary assessment methods) if concentrations levels are below the ...

Influence of meteorological factors on air pollution concentration for a coastal region in India

A long-term study of measurement of concentration of NOx, SO2 and TSP pollutants have been done in a port and harbour region in India. Monthly measurements of gaseous and particulate pollutants were made at six monitoring stations from January 1997 to December 2000. Meteorological data was also simultaneously collected. In this study, the relationship between monitored ambient air quality data ...

First evaluation of a novel screening tool for outlier detection in large scale ambient air quality datasets

Systematic collection of long term meso- to large-scale datasets of ambient air quality provides an indispensible means for air pollution monitoring. However, the quality of these monitoring data depends on the chosen method of measurements and the QA/QC procedures applied. We present the first version of a prototyped screening tool for the automatic detection of outliers in large data volume ...

Mesoscale controls on particulate matter pollution for a mega city in a semi-arid mountainous environment: Tehran, Iran

Tehran, the mega-city capital of Iran, suffers from high concentrations of PM10 throughout the year. Emissions from transport combined with mesoscale atmospheric features related to the mountainous terrain lead to a distinctive diurnal pattern in concentrations. Air quality data from monitoring stations show that the highest concentrations of PM10 are in the morning and evening periods, ...

Remote monitoring of Indoor Air Quality (IAQ)

Indoor air quality (IAQ) relates to a number of environmental factors inside a building that can impinge on the health, comfort, or work performance of the building’s occupants. Monitoring IAQ is vital because it is estimated that the average person spends 90% of their time breathing “indoor air”. Remote monitoring of IAQ sampling data collected by PPM Technology’s ...

EPA establishes new 1-hour standard for sulfur dioxide

On June 2, 2010, the U.S. EPA established a new 1-hour primary National Ambient Air Quality Standard (NAAQS) for sulfur dioxide (SO2). The new 1-hour standard was set at the level of 75 parts per billion (ppb) calculated as the three-year average of the 99th percentile of the annual distribution of daily maximum 1-hour average concentrations. With the establishment of the new 1-hour SO2 standard, ...

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 ...
