High-resolution monthly PM2.5 dataset over Iran from 1980 to 2022

Listed in HKU DataHub and figshare and Loughborough Research Repository — shown once because both records carry DOI 10.6084/m9.figshare.33204750.v4

This dataset provides monthly high-resolution PM2.5 concentrations over Iran from January 1980 to December 2022 at a spatial resolution of 0.1°×0.1°.

Description

The dataset was generated using an AI-based multi-source reconstruction framework incorporating the Multi-Scale Residual Attention Network (MSRA-Net). The reconstruction integrates aerosol information from MERRA-2, meteorological variables from ERA5, topographic information from ETOPO 2022, and satellite-derived PM2.5 constraints from SatPM2.5.

Ground-based PM2.5 observations from monitoring stations in Iran were further used for bias correction and independent evaluation.The monthly reconstructed PM2.5 fields have been consolidated into a single data file to facilitate storage and reuse. The file includes a time index corresponding to each monthly record from 1980-01 to 2022-12, allowing individual months to be identified and extracted directly.

PM2.5 concentrations are expressed in µg m-3.This dataset was generated in support of the study “AI-driven high-resolution air pollution reconstruction from sparse multi-source evidence” and is intended to support long-term air-quality analysis, exposure assessment, environmental-health research, and climate–air quality studies.
