ADMLC report on source term sensitivity in dispersion models
CERC's consultancy team, with GT Science & Software Ltd, has carried out a High Level Review of the Sensitivity of Dispersion Model Predictions to Individual Source Term Parameters. The work was funded by the UK Atmospheric Dispersion Modelling Liaison Committee (ADMLC). Defining source terms is an essential part of dispersion modelling. A substance can be released into the atmosphere in ...

CERC at the Recent Harmo Conference in Budapest
Two of our team, Managing Director Dr David Carruthers and Stephen Smith, recently attended the 17th Harmo conference in Budapest. This conference aims to harmonise approaches to atmospheric dispersion modelling and model evaluation. They presented work on modelling agricultural and bioaerosol emissions with non-point sources and on a validation study of NOx plume chemistry in ADMS. Prof. Sarav ...

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 ...

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 ...

ADMLC report on dispersion from agricultural sources published
‘A review of the limitations and uncertainties of modelling pollutant dispersion from non-point sources’ was published earlier this year. This report presents a detailed literature review, including a summary of agricultural and bioaerosol source parameter ranges particularly of interest to those modelling multiple releases from low-level sources in the vicinity of farm sheds. ...

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 ...

Radioactive iodine in Arctic sea ice may have European origin
Ninety-eight per cent of radioactive iodine in Arctic sea ice may come from Europe, new research suggests. The study concludes that atmospheric transport of Iodine-129 from European nuclear fuel reprocessing plants is the most likely source. Iodine-129 (129I) is a long-lived (half-life of 15.7 million years) radioactive form of iodine that occurs naturally in very small amounts. It is highly ...
