- •
The calculated values of urban heat island (UHI) intensity using Landsat LST and hourly air temperature (Tair) are not comparable.
- •
Landsat-LST-based UHI performs best on hot sunny days, while Tair-based UHI has a better chance during the nighttime following a dry sunny day.
- •
The value of UHI intensity can be influenced by the selected indicators, the data used, the acquisition time and the weather conditions.
