incoming solar radiation at various latitudes, indicating the relative

Photosynthetically Active Radiation (PAR).
During the dry season, incoming PAR
at the canopy surface will be equivalent to that in the open pasture (Figure 2)
where it exhibits a normal curve from dawn to dusk, peaking around noon at just
over 2,000 micromoles of photons per square meter (µm/m2).
