The Leaf angle distribution (or LAD) of a plant canopy refers to the mathematical description of the angular orientation of the leaves in the vegetation. Specifically, if each leaf is conceptually represented by a small flat plate, its orientation can be described with the zenith and the azimuth angles of the surface normal to that plate. If the leaf has a complex structure and is not flat, it may be necessary to approximate the actual leaf by a set of small plates, in which case there may be a number of leaf normals and associated angles. The LAD describes the statistical distribution of these angles.

- A Distribuição Angular Foliar da ramagem de uma planta, refere-se à descrição matemática da posição angular das folhas dessa planta. Especificamente, se cada folha for conceptualmente representada por uma pequena chapa achatada, a sua orientação pode ser descrita com os ângulos do zénite e do azimute em relação à superfície normal dessa chapa.

Especificamente, se cada folha for conceptualmente representada por uma pequena chapa achatada, a sua orientação pode ser descrita com os ângulos do zénite e do azimute em relação à superfície normal dessa chapa. Se a folha possuir uma estrutura complexa e não for achatada, é necessário efectuar uma aproximação, através da divisão da folha em pequenas chapas que possuirão um determinado número de normais e ângulos associados. A Distribuição Angular Foliar descreve a distribuição estatística deste ângulos. (pt)
