Impact of Asian Dust Aerosol and Surface Albedo on Photosynthetically Active Radiation and Surface Radiative Balance in Dryland Ecosystems
Figure 6
(a) Surface downwelling PAR as a function of dust optical depth (); (b) same as (a) but for the diffuse PAR component (). Squares denote the use of cropland-2 surface albedo, and diamonds are for grassland. Sun elevation angle is 90°. Dust vertical profile is for mixed layer case.
