M. author Zheng, Z. author UCAR/NCAR - Library publisher Increasing the albedo of urban surfaces, through strategies like white roof installations, has emerged as a promising approach for urban climate adaptation. Yet, modeling these strategies on a large scale is limited by the use of static urban surface albedo representations in the Earth system models. In this study, we developed a new transient urban surface albedo scheme in the Community Earth System Model and evaluated evolving adaptation strategies under varying urban surface albedo configurations. Our simulations model a gradual increase in the urban surface albedo of roofs, impervious roads, and walls from 2015 to 2099 under the SSP3&#8208;7.0 scenario. Results highlight the cooling effects of roof albedo modifications, which reduce the annual&#8208;mean canopy urban heat island intensity from 0.8&#176;C in 2015 to 0.2&#176;C by 2099. Compared to high&#8208;density and medium&#8208;density urban areas, higher albedo configurations are more effective in cooling environments within tall building districts. Additionally, urban surface albedo changes lead to changes in building energy consumption, where high albedo results in more indoor heating usage in urban areas located beyond 30&#176;N and 25&#176;S. This scheme offers potential applications like simulating natural albedo variations across urban surfaces and enables the inclusion of other urban parameters, such as surface emissivity.
