Surface Emissivity in Determining Land Surface Temperature
要旨Land surface temperatures are important in global change studies, in estimating radiation budgets in heat balance studies and as a control for climate models. Land surface temperature (LST) is strongly influenced by the ability of the surface to emit radiation (i.e. surface emissivity). Therefore, knowledge of the surface emissivity is crucial for estimating the radiation balance at the earth surface. In this paper, we will evaluate the use of Landsat data for determining LST in Ho Chi Minh City based on association surface emissivity value with land cover information.
