Dust Event Analysis in Khuzestan, Iran with Satellite and Ground Data from 2018-2022

From 2018 to 2022, this dataset analyzes dust dynamics in Khuzestan Province, Iran, using satellite-derived Aerosol Optical Depth (AOD) and Aerosol Absorption Index (AAI), ground-based PM₂.₅ and PM₁₀ measurements, HYSPLIT trajectory modeling, and wetland assessments. It was created by Alireza Yousefi Kebriya and shared under a CC-BY-4.0 license. The data reveals strong correlations between satellite and ground measurements and links dust peaks to drought, wetland shrinkage, and transboundary inflows.

Use Cases

• Modeling dust source contributions and pathways based on HYSPLIT trajectory clustering and WPSCF/WCWT mapping.
• Correlating wetland shrinkage with aerosol levels based on the described hydrological-air quality states and MNDWI values.
• Validating satellite AOD data against ground-level PM₂.₅ and PM₁₀ concentrations using the reported R² correlations.
• Analyzing seasonal and annual dust transport patterns to Ahvaz based on the identified six major pathways and wind rose analysis.

Strengths

• Includes multi-year temporal coverage from 2018 to 2022.
• Integrates multiple data sources: satellite AOD/AAI, ground PM measurements, trajectory modeling, and wetland area assessments.
• Reports strong validation metrics, such as R² values of 0.79 between AOD and PM₂.₅ and 0.91 between AOD and PM₁₀.
• Quantifies specific environmental thresholds, like the ~500 km² wetland area marking a sharp reduction in dust suppression.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (927.0 B), suggesting it may contain summary or processed results rather than raw observation records.
