I try to study the evolution of heat islands in the Greater Cairo during the period 2002-2016 using MODIS, but, there is one of the researchers assured me that what i will measure is not the urban heat island (UHI), but, by using MODIS data i will measure Surfaceurban heat island (SUHI) because the data sourced from satellite data, not measured from meteorological stations.
Is there a difference between UHI and SUHI ?
