22 Oct 2025Amines chemistry module online training course offered by CERC

CERC are pleased to announce that we offer an updated online training course for ADMS, specifically for the amine chemistry module.

The course covers:

• Introduction to the atmospheric chemistry of amines and N-amine formation
• Overview of the amine chemistry scheme in ADMS
• Using the ADMS amine chemistry module
• The Amine Chemistry User Input Tool

More information about the course can be found here.

CERC's online training courses are extremely popular both in the UK and internationally. If you would like further information about the training courses offered by CERC, and how to book a place, please visit the training schedule on the CERC website, or email training@cerc.co.uk.

CERC are currently carrying out the Environment Agency Carbon Capture Atmospheric N Amines Formation Estimation Tools (CANFET) project. This involves gathering evidence on alternative models for estimating N-amines and devising and applying a methodology for model intercomparison.

CERC previously carried out another Environment Agency-led research project on amine chemistry modelling: Improving Post-Combustion Carbon Capture Air Quality Risk Assessment Techniques.

These and other aspects relating to the amines chemistry module will be covered at this year's ADMS 6 User Group Meeting in Bristol on 26^th November 2025.

22 Sep 2025Clean Air Routes London: a new interactive map for healthier walking and cycling routes

CERC is proud to announce the launch of Clean Air Routes London, a free interactive map developed by Westminster City Council (WCC) and supported by Defra, designed to help people navigate London using routes with the best available air quality. Launched on World Car Free Day, the tool encourages people to walk or cycle while avoiding areas with high pollution levels. By entering a start and end point, users receive up to three route options ranked by air quality, helping them choose the healthiest journey.

Clean Air Routes London is underpinned by CERC's airTEXT air quality forecasting system, which uses our world-leading ADMS-Urban dispersion model to generate street scale forecasts for key pollutants including NO₂ and PM_2.5. The forecasts are updated twice daily and are calibrated using real-time air quality measurements. Under the project, CERC developed an API for WCC delivering near-instant results for walking and cycling routes across Greater London. The API ranks routes based on personal air pollution exposure, which is calculated using journey time, route geometry, and hourly airTEXT pollution data, allowing users to plan cleaner journeys up to three days in advance.

CERC has over 15 years of experience delivering air quality forecasting and alert services, including airTEXT, which serves over 22,000 subscribers across London and the South-East. Our expertise in air pollution modelling, software development, and cloud-based systems ensures that Clean Air Routes London is both scientifically robust and technically resilient.

16 Sep 2025CERC present research at the Harmo23 conference

CERC are presenting recent research studies at the upcoming 23^rd international Harmo conference (Harmo23), to be held in Hamburg, Germany, from 15^th to 19^th September 2025. This conference series is part of an initiative aimed at harmonising dispersion modelling for regulatory purposes.

CERC's Associate Director of Software, Dr Martin Seaton, will present key results from the Thermal Transport of Air Pollution from Regulated Industries (TAPRI) project, commissioned by the English Environment Agency's Chief Scientist's Group. CERC defined thermal flow types and their characteristics, and analysed meteorological, land use and topographical data for selected cases to better understand thermal flows and model their air quality impacts.

CERC Scientist Dr Victoria Hamilton will present results from CERC's work on an inter-comparison of methods for modelling deposition of ammonia from intensive farms.

CERC also contributed to a third presentation at the conference, relating to the project for RIVM on benchmarking nitrogen deposition models.

3 Sep 2025Major new release of ADMS-Urban, ADMS-Roads & ADMS-Airport 5.1

Version 5.1 is a major update of ADMS-Urban, ADMS-Roads and ADMS-Airport with many powerful new features to aid modelling, data processing and visualisation.

ADMS-Urban, ADMS-Roads and ADMS-Airport are comprehensive tools for investigating air pollution, taking account of complex urban morphology including street canyons and road tunnels.

ADMS-Roads is designed primarily for networks of roads that may be in combination with industrial sites, for instance small towns or rural road networks.

ADMS-Urban can model large urban areas providing output from street-scale to urban-scale.

ADMS-Airport has all the features of ADMS-Urban, and can also incorporate all relevant emission sources at airports including using algorithms designed specifically to model dispersion from aircraft engines.

New features include:

• Urban Canopy and Advanced Street Canyon Mapper tools for faster calculation of urban morphology parameters without requiring separate GIS software
• The latest emission factors from Defra's Emission Factor Toolkit, EFT 13.1
• A verification mode for checking model inputs and generating information about the model run
• A shape file (.shp) merging tool, including field adding, deleting and renaming
• Compatibility with ADMS 6 .apl files
• Plus many enhanced usability functions throughout the Mapper and interface.

All the new features are described in detail in the What's New? guides.

Users with support will get this version within the next few working days.
