Do you think sprawling cities or dense cities have higher UHI? Kansas City is one of the least densely populated cities in USA with an Urban Area with a 1.5m population, shaped like a circle with a 60km diameter. Copenhagen has about the same population, 1.4m in the urban area, and its urban area is a circle with only a 14km-ish diameter. If you placed a weather station in a reasonably central park in each of the two cities, which do you think would have the most UHI influence? Like if you put one station in Assistentens kirkegård  And one in Penn Valley Park  |

Like if you put one station in Assistentens kirkegård And one in Penn Valley Park Hmm hard to say. Concrete and asphalt play a huge role in UHI's not just population density. In that shot of Kansas City, the park appears to be adjacent to a lower density commercial/industrial area that is completed impervious concrete and asphalt surface - so even with the lower population density they could be the same or even higher for the KC location. |

Yes, and the distance to "non-UHI" is significantly higher in Kansas City. Dense urban environments create stronger UHI, but large urban environments also create stronger UHI. Copenhagen is like a small asphalt parking lot, whereas Kansas City is like a large concrete parking lot. |
