To modify the Land Use Regression (LUR) model to account for the impact of urban heat islands on air quality disparities in low-income neighborhoods in the Midwest, follow this structured approach:

1. Identify and Incorporate Heat Island Variables

  • Impervious Surfaces: Use satellite imagery to quantify areas covered by asphalt and concrete.
  • Green Spaces: Incorporate Normalized Difference Vegetation Index (NDVI) data to assess vegetation.
  • Building Density: Include data on building height and density from urban planning sources.
  • Population Density and Socioeconomic Factors: Utilize Census data to account for population density and income levels.
  • Heating Emissions: Use energy consumption data and emission factors for heating sources, considering fuel types.

2. Seasonal Considerations

  • Summer Heat Islands: Use satellite-derived land surface temperatures to model increased ozone formation.
  • Winter Heating Emissions: Incorporate emission data from heating sources, accounting for temperature inversions that trap pollutants.

3. Data Sources and Integration

  • Satellite Imagery: For land cover and temperature data.
  • Emission Inventories: For heating and traffic emissions.
  • Ground Measurements: Use existing networks or citizen science for air quality and temperature data.

4. Modeling Techniques

  • Enhanced LUR Model: Add heat island variables to the regression model.
  • Machine Learning: Consider random forests to identify key variables and interactions.

5. Spatial Resolution and Validation

  • High-Resolution Data: Use fine-scale data for precise estimates.
  • Validation: Compare model predictions with ground measurements, focusing on underserved areas.

6. Policy Implications

  • Urban Planning: Advocate for green spaces and cleaner heating sources.
  • Environmental Justice: Highlight disparities and inform policy to mitigate them.

7. Literature Review

  • Existing Studies: Review prior modifications of LUR models for heat islands to inform variable selection and methodology.

8. Consider Interactions and Nuances

  • Interaction Terms: Explore how temperature affects pollutant formation from emissions.
  • Weather Patterns: Account for temperature inversions and cold weather effects on pollution dispersion.

By systematically integrating these elements, the modified LUR model will better address the impact of urban heat islands on air quality in vulnerable neighborhoods, providing a robust tool for environmental and policy decisions.
