New improvements on the OPANA model by using World Wide Web resources

In recent years, an extraordinary interest has grown within the scientific community to improve the operational versions of complex mesoscale urban and regional models. One of the most important limitations of the operational versions of such types of models are found in the convenient updating of boundary conditions for sufficiently long forecasting periods. Downloading boundary conditions from ...

Centralised QA for CEM applications using AQM software

ABSTRACT: This paper illustrates how software developed for ambient Air Quality Monitoring (AQM) applications has been used to provide a readily available and field tested solution for CEM reporting requirements. Data processing to produce CEM compliance reports can be a significant task, requiring greater resource than the operation and maintenance of the CEM equipment itself. Where CEM ...

Buying AQM Equipment or AQ Data? It’s Your Choice

In the traditional approach to air quality monitoring, those “who wants to know” have also owned and maintained the monitoring equipment generating the answers. This approach worked quite fine as long as the user had the budget to invest in the equipment and an organization large enough to maintain it. However, recent years’ slimmed organizations have opened up for an ...

What is the difference between a gas analyser and a gas monitor?

Technically, there does not have to be any difference at all. However, semantically, “analysis” might suggest something more scientific with higher precision and better performance than a simple “monitor” which possibly suggests a more indicative output where precision is of less importance. With that said, the two words “analyser” and “monitor” ...

AQM for Local Authorities: Hidden costs

Legislation and increasing public scrutiny are focusing on the roles and responsibilities of local authorities in air quality management. In 2019 the Guardian published an article stating that five people die each week in Bristol as a result of high levels of air pollution and that “83% of reporting zones in the UK had illegal levels [of air pollution]”. As air quality monitoring ...

AQM at 40°C below Zero!

Most people think of the Arctic as a highly pristine clean environment, but this is not always the case. During the long dark Arctic winter, the urban atmosphere can become extremely polluted. Indeed, at some point during the year, the remote Alaskan city of Fairbanks turns into the most polluted city in the whole of the US. This is due to the very cold Arctic winter when emissions of gases and ...

Air pollution monitoring: a solution for cost effective measurements - Case study

Air pollution is one of the main environmental problems to be addressed by cities worldwide. In order to foster sustainable development and mitigate climate change, it is therefore important to provide national and regional authorities with appropriate measures to reduce criteria pollutants (PM 10, PM2.5, O3, CO, SO2 and NOx) concentrations in ambient air. Many cities are not able of meeting ...
