Semiempirical. kernel-driven linear bidirectional reflectance distribution function (BRDF) models are widely used to characterize vegetation reflectance anisotropy and provide land surface bidirectional reflectance factor (BRF) products at the regional and global scales. However. these models usually imply an assumption of spherical leaf inclination. https://fitnessgravesyardes.shop/product-category/line-filter/
