Surface downwelling par diffuse flux
WebMar 16, 2007 · For example, when the diffuse:total ratio ≤0.33, mean PAR downwelling is ≈1800 μmol m −2 s −1, which is more than twice the incident PAR as when the diffuse:total ratio >0.66. Thus, when the diffuse:total ratio is low, photosynthesis at the top of the canopy is light-saturated (lowest LUE) and the rest of the canopy is either poorly ... WebTwo downwelling PAR field components can be distinguished under a clear sky: the quasi-parallel direct beam arriving from the direction of the sun (with PAR irradiance on a horizontal surface I PAR,dir) and the diffuse sky radiation arriving from all upward directions not blocked by topography (I PAR,diff).
