Impact of Asian Dust Aerosol and Surface Albedo on Photosynthetically Active Radiation and Surface Radiative Balance in Dryland Ecosystems
Figure 7
(a) Diffuse fraction (α) of PAR, and (b) the ratio of PAR to downwelling shortwave radiation, , as a function of sun elevation angle. Dust loading is μg m−3. Dust vertical profile is for the mixed layer case. The surface albedo is for the cropland-2 case.
