Figure 2.

Panel (b) shows the recorded incident photosynthetically active photon flux on 20 August 2019, above the soybean canopy of Figure 1, which was an intermittently cloudy day. Panel (a) shows the predicted light intensity for the same day based on sun–earth geometry and an atmospheric transmittance of 0.85, assuming a cloud‐free clear‐sky day. The diurnal light absorption simulated for single pixels on the leaves in the top, middle and bottom of the soybean canopy on the sunny day are shown in panels (c), (e) and (g), respectively, and for the cloudy day in panels (d), (f) and (h), respectively.
