Abstract
Albedo value in Osaka city was computed by using LANDSAT/MSS satellite data. When building coverage exceeded 0.3, albedo value was a constant of 0.12 regardless of building height, and had the convex curve with the minimum value at 0.35 of building coverage. When building height was less than 10m, albedo value varied widely. However when building height was larger than 10m, albedo value decreased slightly regardless of building coverage. Next albedo value was calculated by using urban canopy model. Albedo values obtained from both LANDSAT/MSS satellite data and urban canopy model agreed reasonably. This result suggested that urban canopy model was accurate.
