WRF-Chem Parameter Configurations for Organic Aerosol Sensitivity Study in Delhi

Parameter configuration files for a sensitivity study of the WRF-Chem model's predictions of organic aerosol mass loadings and composition. The dataset, created by Douglas Lowe of the University of Manchester, investigates 10 parameters across 5 production processes for anthropogenic and biomass burning organic aerosols. It includes a template namelist for a modified version of WRF-Chem 3.8.1.

Use Cases

• Sensitivity analysis of organic aerosol model predictions based on the 10 perturbed production parameters.
• Calibrating the volatility basis set (VBS) approach in atmospheric models based on parameters like VBS aging rate and SVOC volatility distribution.
• Investigating the relative impact of anthropogenic versus biomass burning emissions on organic aerosol composition based on the described scaling factors.
• Benchmarking modified versions of WRF-Chem against standard model outputs using the provided configuration template.

Strengths

• Focuses on 10 specific parameters for sensitivity analysis, providing a structured experimental setup.
• Includes a template namelist for integration with a modified WRF-Chem 3.8.1 model.
• Parameters have defined ranges and units, such as the VBS_AGERATE in cm³ molec.⁻¹ s⁻¹ and SVOC_VOLDIST as a dimensionless 0-1 value.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred from the description after download.
• Last update date is unknown; freshness unverified.
