          <dc:description>&lt;p dir="ltr"&gt;This dataset provides monthly high-resolution PM&lt;sub&gt;2.5&lt;/sub&gt; concentrations over Iran from January 1980 to December 2022 at a spatial resolution of 0.1°×0.1°. 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 PM&lt;sub&gt;2.5&lt;/sub&gt; constraints from SatPM&lt;sub&gt;2.5&lt;/sub&gt;. Ground-based PM&lt;sub&gt;2.5&lt;/sub&gt; observations from monitoring stations in Iran were further used for bias correction and independent evaluation.The monthly reconstructed PM&lt;sub&gt;2.5&lt;/sub&gt; 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. PM&lt;sub&gt;2.5&lt;/sub&gt; concentrations are expressed in µg m&lt;sup&gt;-3&lt;/sup&gt;.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.&lt;/p&gt;</dc:description>
