Currently the AGDISP model has two possible ways for describing plant canopy structure. The LAI model assumes that the foliage is homogeneously distributed in a horizontal plane, and requires leaf area index and vertical foliage distribution as input. The other approach, the Story model, assumes the plant canopy is made up of a given number of identical plants with their crowns made up of a number of cylindrical layers. The probability of penetration through each cylinder is required.
