PM2.5 concentration per LAD in 2016
Dataset
Summary
Description:
This dataset provides the average annual and monthly PM2.5 concentrations in µg/m³ aggregated to Local Authority District (LAD) level for the period 01-01-2016:31-12-2016 for the United Kingdom. The underlying source data is the global PM2.5 product (V6.GL.02.04) at 0.01° x 0.01° (approximately 1km x 1km) spatial resolution, published by Shen et al.(2024). The aggregation was performed using the LAD boundaries (2021) by calculating the weighted mean of all grid cells falling within each LAD geography.

Documentation
Documentation:
The dataset contains 15 variables for each LAD: the annual mean PM2.5 concentration in µg/m³ (pm2.5_mean), 12 monthly mean PM2.5 concentrations in µg/m³ (pm2.5_mean_01 to pm2.5_mean_12), the LAD regional code (geo_code), and a LAD regional name (geo_label). This data is provided in two distinct formats: a CSV file, which contains the tabular data; and a GPKG file, a geospatial format that combines the tabular data with the LAD boundary geometries.

Purpose:
The underlying methods and source information used to construct the
pre-processed dataset are documented in the following paper: Shen, S., Li, C.,
van Donkelaar, A., Jacobs, N., Wang, C., Martin, R. V.: Enhancing Global
Estimation of Fine Particulate Matter Concentrations by Including Geophysical a
Priori Information in Deep Learning. (2024) ACS ES&T Air. DOI:
10.1021/acsestair.3c00054. PM2.5 concentration estimates combine
satellite-derived Aerosol Optical Depth (AOD) from multiple instruments like
MODIS/VIIRS, GEOS-Chem chemical transport model simulations, and ground-based
monitor observations. The AOD and model outputs are fused using relative
uncertainties calibrated by AERONET ground-based sun photometer data. The
aggregation was performed by the Imago Team.
