Abstract
Remote sensing is a key application in global-change scienceand urban climatology. Urbanization, the conversion of other types of land to uses associated with growth of populations and economy has a great impact on both micro-climate as well as macro-climate.Urban areas tend to experience a relatively higher temperature compared with the surrounding rural areas. This thermal difference, in conjunction with waste heat released from urban houses, transportation and industry, contribute to the development of urban heat island (UHI). The aim of this study is to examine the changes in land use/cover pattern in a rapidly changing area of Bucharest metropolitan area in relation to urbanization since the 1984s till 2005 and then to investigate the impact of such changes on the intensity and spatial pattern of the UHI effect in the region.Investigation of radiation properties, energy balance and heat fluxes is based on satellite data from various sensors Landsat TM, ETM+, ASTER and IKONOS.So called effect of "urban heat island" must be considered mostly for summer periods conditions and large European scale heat waves.
