This study was conducted to estimate the fraction of Intercepted Photosinthetically Active Radiation (fIPAR) in an olive orchard. The method proposed to estimate fIPAR in olive canopies consisted of a coupled radiative transfer model that linked the 3D Forest Light Interaction Model (FLIGHT) and the Orchard Radiation Interception Model (ORIM). This method was used to assess the estimation of instantaneous fIPAR as a function of planting grids, percentage cover, and soil effects. The linked model was tested against field measurements of fIPAR acquired for a commercial olive orchard, where study plots showing a gradient in the canopy structure and percentage cover were selected.
