Air Quality and Dust Dynamics in Khuzestan, Iran from 2018 to 2022

PM₂.₅ concentrations ranged from 12 to 750 µg/m³ and PM₁₀ from 10 to 800 µg/m³ in this study of dust events in Khuzestan Province, Iran. The dataset, authored by Alireza Yousefi Kebriya and last updated in 2026, integrates satellite-derived Aerosol Optical Depth (AOD), ground-based particulate matter data, HYSPLIT trajectory modeling, and wetland area assessments from 2018 to 2022. It reveals strong correlations between satellite and ground data and identifies six major dust pathways to Ahvaz.

Use Cases

• Modeling dust source contributions and pathways based on HYSPLIT trajectory clustering and WPSCF/WCWT mapping.
• Correlating satellite Aerosol Optical Depth (AOD) with ground-level PM₂.₅ and PM₁₀ measurements for validation.
• Analyzing the impact of wetland shrinkage (Hoor al-Azim) on local air quality and dust suppression thresholds.
• Identifying transboundary dust inflow patterns from Iraq and Syria into Iran using wind rose and trajectory analysis.

Strengths

• Integrates multiple data sources: satellite AOD/AAI, ground PM, trajectory modeling, and wetland remote sensing.
• Covers a five-year time range from 2018 to 2022, capturing temporal variability.
• Reports strong statistical correlations, such as R²=0.91 between AOD and PM₁₀.
• Provides specific geographic focus on Khuzestan Province, Iran, with identified dust pathways.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 5.5 KB, suggesting limited scope or highly summarized data.
