The algorithm first uses the canopy BRDF model to express the canopy reflectance as a function of a series of parameters such as Lai / fAPAR, wavelength, soil and leaf reflectance, aggregation index, incidence and observation angle. For several key parameters, a parameter table is established as the input of inversion. Then input the preprocessed surface reflectance data and land cover data, and use the look-up table (LUT) method to retrieve the fAPAR product. The data contains 11 TIFS and a PNG image.</p>",
