Pandolfo开发的一个数值模型被用来计算由于城市化引起的地表物理特性的变化以及由于增加了具有辐射活性的污染物（如碳质气溶胶）而引起的温度变化，这些污染物是城市化和工业化的特征。通过（1）忽略平流，（2）保持污染物浓度随时间变化恒定，简化了模型。结果表明，地表物理性质的变化，而不是污染物是造成城市热岛的主导因素。垂直热结构的变化是由近地表温度的变化和较高层污染物的存在引起的。
A numerical model developed by Pandolfo was used to compute changes in temperature resulting from changes in the physical characteristics of the surface due to urbanization and from the addition of radiatively active pollutants, such as a carbonaceous aerosol, that are characteristic of urbanization and industrialization. The model was simplified here by (1) omitting advection, and (2) by holding the pollutant concentration constant in time. The results show that changes in the physical properties of the surface, and not pollutants are the dominant factors in creating the urban heat island. Changes in the vertical thermal structure are caused by changes in the surface temperature near the surface and by the presence of pollutants at higher levels.
