Improving Land Surface Pixel Level Albedo Characterization Using Sub-Pixel Information Retrieved from Remote Sensing

Surface albedo plays an important role in climate model simulations. Current climate models usually use simplified approaches to calculate albedo and can not take sub-grid heterogeneity into account. For heterogeneous land areas, retrieving large scale surface albedo by using current albedo characterization schemes can cause considerably spatial scaling bias. The scaling biases in the albedo estimation processes mainly result from overlooking …
