CERC at the Recent Harmo18 Conference in Bologna
David Carruthers and Amy Stidworthy recently attended the 18th Harmo conference in Bologna. This international conference aims to harmonise approaches to atmospheric dispersion modelling and model evaluation. They presented two papers: firstly on work using sensor data and inversion techniques to systematically reduce dispersion model error, including a Cambridge case study using CERC's ...

Investigating emission limits for the Norwegian Environment Agency
The Norwegian Environment Agency has commissioned CERC to study how air concentration benchmarks for specific metals and polycyclic aromatic hydrocarbons (PAHs) correspond to annual emissions to air from a particular source. In Norway, the major industrial sources of these emissions are non-ferrous metal industries such as aluminium and manganese production. Other contributors include graphite ...

Can I use NWP met data for dispersion modelling?
CERC has been commissioned to carry out an investigation into the use of Numerical Weather Prediction (NWP) met data in atmospheric dispersion modelling. CERC's consultancy and scientific research teams will focus on modelling carried out for planning and permitting under EPR, whilst the UK Health Security Agency (UKHSA) will target probabilistic accident consequence assessments. The project will ...

New review of odour emissions modelling with model intercomparison
Dispersion modelling plays an important role in the assessment of potential odour annoyance for planned activities and the investigation of complaints related to existing facilities. However, compared to general air pollution modelling there are particular challenges associated with modelling odour dispersion and exposure due to the importance of odour variations over short timescales to the ...

CERC Completes Comprehensive Air Quality Assessment for Johnson Matthey, Royston
CERC have used ADMS 5 to carry out dispersion modelling for all relevant processes on Johnson Matthey's Royston site. Impacts on both human health and natural habitats were assessed, including nitrogen and acid deposition at nearby Sites of Special Scientific Interest (SSSIs). The site is complex: there are many emission points and buildings to be taken into account, and terrain effects are ...

Pollution investigation at Wellington Civic Centre
The CERC consultancy team investigated potential sources of high levels of pollution at Wellington Civic Centre offices. In work commissioned by Telford & Wrekin Council, ADMS 5 was used to carry out dispersion modelling of emissions from flues serving the leisure centre adjacent to the offices. CERC determined which sources were responsible for the high pollution levels and supported the ...

Air Quality Monitoring Network Contract Awarded to OPSIS
OPSIS AB has been commissioned by Kuwait Oil Company (KOC) to assess the impact of KOC:s operations in the state of Kuwait. A network of air quality monitors will be managed. Emissions to the air from KOC:s operations will be reported. A dispersion model will be used to determine the impact from KOC:s operations to the air quality in Kuwait. The project will continue for five years. ...
