Abstract:
A fusion of Landsat and MODIS products is used in the Simple Biosphere model (SIB2) to describe the urban and vegetation characteristics over the U.S. We assess the urban heat island occurrence and amplitude and the impact of urbanization as a form of land use on the surface energy, carbon and water cycles for year 2001. Interactions between urban and different vegetation classes was assessed for better understanding the vegetation control on UHI hourly and seasonal dynamics. UHI analysis over several urban centers will be presented as well as an aggregate impact of urban lands on the surface temperature, carbon and water cycles over the continental United States.
