Abstract

The National Physical Laboratory (NPL) is contracted to manage the UK Particle Concentrations and Numbers (PCN) and Black Carbon (BC) Network. The PCN&BC Network measures and reports concentrations and chemical composition of particles in ambient air across the UK, with a focus on PM2.5 (particulate matter with an aerodynamic diameter < 2.5 µm).

This report was prepared by NPL and the Environmental Research Group at Imperial College London as part of the PCN&BC Network contract. The contract is managed by the Environment Agency on behalf of the Department for the Environment, Food and Rural Affairs and the Devolved Administrations: the Scottish Government, the Welsh Government, and the Department of Agriculture, Environment and Rural Affairs in Northern Ireland (DAERA).

This 2024 annual report contains:

- A summary of the Network structure, its operation, and quality procedures.
- Descriptions of the instruments used on the Network.
- The data capture recorded for each instrument.
- Time series plots of all ratified Network data in 2024.
