Abstract

The dependence of surface albedo on surface structure is investigated in the central parts of 23 urban areas in the Kanto Plain, Japan. The surface albedo is inferred from LANDSAT/MSS data collect-ed on 5 November 1990, using Nakagawa and Ooi's (1992) method. The surface structure in the cen-tral part of the urban area is measured in terms of both sky view-factor and building-land ratio, which are regarded as substitutions for Aida and Gotoh's (1982) .parameters H/Wf and Wr/Wf respec-tively. As a result, it is found that the surface albedo is relatively high in cases of remarkably high or low building-land ratios, and that the surface albedo clearly decreases with decreasing sky view-factor. It is also found that the surface albedo in the central part of the urban area clearly decreases with increasing daytime population density. The dependencies of surface albedo both on surface struc-ture and on daytime population density of urban area are derived from the clear dependence of sur-face structure parameters of the central part of the urban area on its daytime population density.
