The Atmospheric Dispersion Modelling Liaison Committee held a one-day workshop on 12 March 2020 at the Centre for Radiation, Chemicals and Environmental Hazards (CRCE), PHE, Oxfordshire.

The aim of the workshop was to bring together dispersion modellers, policy experts and decision-makers to discuss the role of dispersion modelling in emergency planning and response across different contaminant types. Key objectives were to:

  • Look at current practices in emergency planning and response modelling across different contaminants, including radiological, chemical, volcanic ash, fire and smoke.
  • Assess the differences in scientific approaches and explore reasons for these, for example whether they arise from historical development, or from the nature of the underlying emergencies (timescales, distances affected, ease of identifying the contaminant etc)?
  • Examine differences in planning at a policy level (the use of ‘reasonable worst case’, probabilistic approaches) and any implications of this for response.
  • Discuss whether emergency response and planning can benefit from joint working – and, if so, how this could be taken forward.

The workshop included talks from distinguished speakers including Professor Robin Grimes FRS FREng (MOD Chief Scientific Advisor), Professor Jonathan Rougier and representatives from the Met Office, Public Health England, Office for Nuclear Regulation and the Health and Safety Executive. The programme is attached. And links to the presentations are listed below:

A record of the four questions posed to the audience, attendees answers to those questions and the subsequent discussion is currently being drafted and will be posted here shortly.
