We extend the multiple scattering formalism of Shettle and Green using a turbid atmosphere of uniform horizontal layers with vertical nonhomogeneities by introducing uniform cloud, haze, and smog layers. Our solution follows the rigorous equations of Chandrasekhar. The fact that it is capable of handling a cloud layer of large optical thickness with minimal… (More)
Two image processing projects are presented for introductory students that require only minimal computer facilities. The first produces a binary (black or white pixel) image and introduces signal processing concepts. The second project extends these ideas to the production of a grey level image.
