Abstract
Land Surface temperature (LST) is one of the most important variables for determining the state within the climate system. Thermal infrared (TIR) remote sensing used to monitor air temperature and affecting microclimate in urban areas. TIR remote sensing techniques have been applied for analyzing LST patterns and its relationship with surface characteristics, assessing urban heat island (UHI), and relating LST with surface energy fluxes to characterize landscape properties and processes. In the present study, a remote sensing was combined with a geographic information system (GIS) environment for determine the impact of industrial areas on Surface Temperature using of TIR Remote Sensing through Landsat ETM+ data (band 6.1) and comparing the relationships between urban surface temperature and land cover types in Jubail City in Saudi Arabia. The study showed the increase of urban surface temperature near the industrial area in comparison with suburban areas. The center of the heat island was concentrated above the industrial area and its adjacent urban areas. Iron and steel factories raise the temperature to 80°C which affects air temperature of nearby areas. This effect may extend to the buffer zone area ranging from 500-2000 m

Land Surface temperature is one of the most important variables for determining the state of the climate system
This research aims to evaluate the use of Landsat ETM+ data for identifying temperature differences in urban areas, to analyze and compare the relationship between urban surface temperature and land cover types, and to estimate the impact of industrial areas upon adjacent area
The Landsat 7 ETM+ was acquired on 18 May, 2001, Band combination of 7, 4, 2 was used to give maximum information of land cover/use relevant to the investigated area, i.e. industrial zone, residential area of inner city with high density and its expansion, gardens, sand and water
Summary
Land Surface temperature is one of the most important variables for determining the state of the climate system. The Urban Heat Island (UHI) is the important phenomenon in urban geographic studies, which traps heat in thermal mass like asphalt, concrete, bricks, stones and roads, which absorb, store and re-emit this heat to the urban air at night [3], the urban temperatures are 2-5 higher than those in a rural surroundings [4]. It is a key variable for the detection of climate change and assessing the relative importance of anthropogenic and natural influences. The urbanization and industrialization are a main factor for island heat
