Dust Trajectory Clusters and Air Quality for Khuzestan, Iran (2018-2022)

Khuzestan Province, Iran, from 2018 to 2022. This dataset contains the percentage share of dust trajectory clusters to Ahvaz, derived from HYSPLIT modeling, satellite Aerosol Optical Depth (AOD), and ground-based PM data. It was created by Alireza Yousefi Kebriya and last updated in May 2026.

Use Cases

• Identify primary dust source regions and pathways based on trajectory clustering percentages.
• Correlate wetland shrinkage with dust event intensity based on the described area and AOD relationship.
• Model transboundary dust transport using the identified dust belt and secondary zones from WPSCF/WCWT mapping.
• Assess satellite data reliability for ground-level PM monitoring based on the reported R² correlations.

Strengths

• Strong correlations reported between satellite AOD and ground PM₂.₅ (R²=0.79) and PM₁₀ (R²=0.91).
• Multi-year temporal coverage from 2018 to 2022, capturing variability linked to flooding and drought.
• Integrates multiple data sources: satellite AOD/AAI, ground PM, HYSPLIT trajectories, and wetland assessments.

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 (5.5 KB), indicating limited scope or highly aggregated summary data.
