 The study uses high-resolution air temperature data from an urban meteorological network in Birmingham, UK to quantify and identify the spatial pattern of daytime and nighttime urban heat island, UHI, in the city. The analysis shows that surface UHI is linked to land use while canopy UHI is influenced by effective processes. Strong relationships were found between air temperatures and LST at a neighborhood scale but limited at the city scale with the use of higher-resolution urban meteorological data sets.
