LAEI 2006: Modelled Air Pollution Concentrations for London at 20m Grid Points

Point locations at 20 metre grid spacing represent the centre of a 20m by 20m square for mapping modelled concentration values. The dataset is provided by the Greater London Authority and was last updated on the platform in March 2026. It can be linked to modelled values datasets using a GRID-ID field.

Use Cases

• Mapping historical air pollution concentrations based on the 20m grid point locations.
• Linking modelled pollution values to spatial points using the GRID-ID field mentioned in the description.
• Analyzing the spatial distribution of pollutants for the 2006 reference year in London.

Strengths

• High spatial resolution with points at 20 metre grid spacing.
• Explicit link to modelled values via a GRID-ID field.

Limitations

• Dataset has been superseded by newer releases, as noted in the description.
• Column-level documentation is absent; field semantics must be inferred after download.
