The system enables you to implement best practice quality assurance procedures, providing value and confidence in data – critical where air quality data are to be used to support decision-making or demonstrate regulatory compliance.

MODUS allows high volumes of data to be managed through real-time data analysis screens, custom workflows and user-configurable task-allocation options. This means final datasets and associated analysis, reporting and interpretation are delivered to deadlines and defined quality standards – and are supported by a transparent audit trail.

MODUS is highly scalable, making it the ideal solution for local, regional and national measurement networks – capable of managing billions of data points every year from hundreds of measurement stations. Clients include the UK Government; the devolved administrations in Scotland, Wales and Northern Ireland; and the Government of Gibraltar. MODUS is used to deliver data analysis for major cities including Riyadh and London. It is fully compliant with reporting requirements across the globe, including US Environmental Protection Agency and EU regulatory regimes, with the flexibility to configure the solution to meet user needs.


Ricardo also offers clients the option of a fully managed service, which means our team of air quality experts looks after network data from initial generation to the production of bespoke analysis, interpretation, reporting and dissemination.
