National Physical Laboratory

Million pound investment in emissions monitoring

The National Physical Laboratory (NPL) is investing over £1 million in a new mobile instrument to remotely monitor airborne emissions. This new investment represents one of the most significant made by NPL in recent times.

DIAL van

The new mobile system will be based on Differential Absorption Lidar (DIAL), which can provide rapid, accurate measurements of emissions up to 1 km away from industrial plants. State-of-the-art infrared and ultraviolet light technology enables the system to pinpoint the source of emissions and visually represent them as a 3D map.

NPL currently has one DIAL facility, mounted on the back of an articulated lorry, which has carried out measurements as far away as the USA and more recently in the Port of Rotterdam, the Netherlands, where it was used to detect the source of a benzene leak. The new investment is strongly supported by the success of this current system.

The new DIAL facility will strengthen NPL's capability in remote emissions monitoring and will contribute to the work of the Centre for Carbon Measurement at NPL, which aims to reduce uncertainties in climate data and provide the robust measurements required to account for, price and trade carbon emissions.
