In the present study, we aim at developing an empirical model of BRDF over Tokyo, Japan, which is one of the
most polluted areas in Asia, to evaluate the effect of the surface albedo on air-pollution monitoring from space.
We used the RossThick-LiSparseReciprocal model with MODIS data to retrieve BRDF information. The BRDF
had a strong dependence on season and local time, and the magnitude of the seasonal and local time change was
up to 50%.
