air monitoring data Articles

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 ...

Introduction Valid inter-comparisons of operating performance parameters among all members of the nuclear industry are essential for the implementation of continuous improvement and for obtaining credibility among regulators and the general public. It is imperative that the comparison of performances among different industry facilities be as accurate as possible and normalized to ...

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 ...

As part of a new Air Quality and Meteorology Network in the Dominican  Republic, Pueblo Viejo Dominicana Corporation (PVDC) have committed to implementing four automated air quality data monitoring systems. Three stations are already in place, with a fourth to be added pending site location approval. The stations are installed and maintained by Golder Solutions, the successful  vendor ...

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 ...

This paper presents the application of the Integrated Transport Effect Modelling System (ITEMS) in the city of Kaunas, Lithuania, taking into consideration some factors such as existing vehicle fleet, traffic flows, and ambient air quality monitoring data. The objective of this study is to estimate the exhausts of CO, NOx, and SO2 released by motor vehicles in relation to predictive traffic ...

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 ...

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 ...

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 ...

In recent screen-to-screen conversations with industry leaders three words keep coming up in respect to air monitoring on construction sites: Resilience, Remote and ConTech. For the construction sector to survive and thrive beyond COVID-19, companies must implement systems-thinking approaches which mitigate risks to people and ...

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 ...

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 ...

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, ...

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, ...

Abstract Air in-leakage into the steam space of a condenser can become stored in pockets of high partial pressures that negatively impact condenser performance and become a source of dissolved gases in the feedwater. These pockets can be configuration caused and generally cannot be eliminated by reducing air ingress or increasing venting capacity. Fortunately, engineering designs are ...

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 ...

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 ...
