Abstract
Relations between various definitions of albedo for a layer of random discrete scatterers are established. Albedo and attenuation values are obtained for soybeans and corn using a discrete model. Attenuation values are also obtained using an empirical approach. Brightness temperatures, computed by transport theory with these albedo and attenuation values, are compared with the measured brightness temperature values for soybeans and corn
