Article preview. Near-Field Energy Transport.In modeling the canopy reflectance of row-planted crops, neglecting horizontal radiative transfer may lead to an inaccurate representation of vegetation energy balance and further cause uncertainty in the simulation of canopy reflectance at larger viewing zenith angles. To reduce this systematic deviation, here we refined the four-stream radiative transfer …The General Vector Radiative Transfer Equation. The next simplifying step is to go from the world of electric and magnetic fields to the world of radiance. At optical wavelengths, the frequency of electromagnetic waves (light) is of order 1 0 1 5 Hz. This is far higher than can be directly measured for a time-dependent propagating E field. ….
