The variability of forest reflectance among hemiboreal forests can be described with a fewbasis functions. Five basis functions describe almost 98% of variability of directional reflectancespectra in the optical spectral domain (400−1700 nm) in forest stands at the top of a canopy in nadir. A statistical forest reflectance model (SFRM) was developed. the input parameters of whic... https://fitnessgravesyardes.shop/product-category/swing-arm/
