文摘

•: An optimal sampling strategy was designed over the heterogeneous surface.
•: An automatic measuring system based on WSN technology was proposed.
•: An upscaling transformation was established to upscale in-situ albedo measurement.
•: The coarse-pixel scale WSN-based albedo observation was established.
•: A validation strategy of coarse scale albedo products was proposed.
