Assessing surface albedo change and its induced radiation budget under rapid urbanization with Landsat and GLASS data

Radiative forcing (RF) induced by land use (mainly surface albedo) change is still not well understood in climate change science, especially the effects of changes in urban albedo due to rapid urbanization on the urban radiation budget. In this study, a modified RF derivation approach based on Lands...
