Urban Surface Heat Model

Urban areas are known for their "heat island" effect, where cities tend to be warmer than their rural surroundings. To tackle this issue, I undertook a project as part of my matura examination to simulate surface temperatures in urban environments using computer modeling. This simulation can help us explore new methods of natural cooling for cities before implementing them in real life, potentially saving time and money.

The Objective

The goal of my project was to create a computer model capable of analyzing surface temperatures in urban areas. By doing this, we can identify areas that are most affected by heat and target them for cooling interventions without relying solely on costly and extensive measurements.

The Approach

I developed the simulation using JavaScript, incorporating key factors such as:

  • Solar Radiation
  • Evapotranspiration
  • Heat Diffusion
  • Heat Convection
  • Using this model, I simulated two different scenarios and created heat maps of the urban areas in question. These simulated heat maps were then compared to actual measured heat maps of the same areas.

    Findings

    The comparison revealed that my model could realistically depict the distribution of surface temperatures, considering the physical properties of various surfaces. While the specific temperature values from the simulation differed somewhat from the measured values, the model effectively provided a general overview of the heat distribution within urban settings.

    Conclusion

    The comparison revealed that my model could realistically depict the distribution of surface temperatures, considering the physical properties of various surfaces. While the specific temperature values from the simulation differed somewhat from the measured values, the model effectively provided a general overview of the heat distribution within urban settings.
