Abstract
The urban heat island (UHI) is a recognized signature of the urban climate, however beyond this characterization; it isstill a relevant phenomenon to study in urban design. In this paper, we seek to characterize UHI in differing urbanforms, comparing air and surface temperatures to characterize Air UHI (AUHI) and Surface UHI (SUHI) respectively.The analysis site corresponds to the districts of Casablanca, Morocco's largest city, covering coastal and centralneighborhoods with different urban planning styles. We used land surface temperatures (LST) from the Landsat-8satellite and both observed and simulated air temperatures from the Copernicus reanalysis. We argue that LST isalways higher than air temperature and that there is a shift between SUHI and AUHI that we have quantified fordaytime and nighttime monitoring. We also concluded that UHI depends on four criteria: location, land use, buildingheight, and road width.
