    "abstract": "Various numerical methods exist for obtaining the radiances inside a canopy\nof leaves above a partly reflecting ground. In view of testing the accuracy of\nthese diverse methods, it is desirable to have at one\u0027s disposal non-trivial\nmodels possessing analytical solutions, against which to compare numerical\nreuslts. Such models are obtained in the present paper, for the case of a\nhorizontally homogeneous foliage of Lambertian leaves, modeled as a turbid\nmedium. Our treatment is more general than usual in that we allow the top and\nunder sides of leaves to have different optical coefficients. Besides being\nmore realistic, this enables artificial situations, such as extreme light\ntrapping, testing the limits of various numerical methods.",
