The retrieval of sun-induced fluorescence (SIF) from hyperspectral radiance data grew to maturity with research activities around the FLuorescence EXplorer satellite mission FLEX. yet full-spectrum estimation methods such as the spectral fitting method (SFM) are computationally expensive. To bypass this computational load. this work aims to approximate the SFM-based SIF retrieval by m... https://danddcollectiblers.shop/product-category/activity-toy/
