PALM Air Quality Simulations for Mäkelänkatu, Helsinki with Multiple Boundary Conditions

Helsinki, Finland air quality simulations using the PALM model system 6.0 for Mäkelänkatu. The dataset contains model input, output, and performance measures from simulations on specific dates in June and December, comparing modelled and measured boundary conditions. It was created by Mona Kurppa of the University of Helsinki.

Use Cases

• Compare air pollutant dispersion under modelled versus measured meteorological boundary conditions.
• Analyze the impact of measured wind direction corrections on simulation results.
• Validate the PALM model system's performance for specific urban street canyon scenarios.
• Study aerosol size distribution dynamics using input from the SMEAR III station.

Strengths

• Simulations are conducted for a specific urban location (Mäkelänkatu, Helsinki).
• Includes multiple simulation scenarios comparing different boundary condition sources (MEPS, ADCHEM, Kivenlahti mast, SMEAR III).
• Data is provided for root, parent, and child computational domains, suggesting a nested modeling approach.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count, file formats, and column-level documentation are absent.
• Last update date is unknown; freshness unverified.
