摘要：

For investigation of the angular distribution of plant canopy reflectance with high angular resolution, a special field goniometer was designed. The measured distributions for barley and red clover canopies in the red and near infrared spectral regions, including hot-spot profiles during vegetative growth, are reported. The dependence of four vegetation indices on nadir angle significant in off-nadir radiance measurements is studied, too.
