Over the last 40 years. the light use efficiency (LUE) model has become a popular approach for gross primary productivity (GPP) estimation in the carbon and remote sensing communities. Despite the fact that the LUE model provides a simple but effective way to approximate GPP at ecosystem to global scales from remote sensing data. when implemented in real GPP modelling. https://cuttingedgecutleryco.shop/product-category/fillet/
