Cover Story: Mixed pixels are common in medium- and low-resolution satellite imagery, and the widely used linear mixing model helps approximately decompose them into individual land cover components after atmospheric correction, bridging spectral resolution gaps. This study presents a method to enhance multispectral surface reflectance by reconstructing additional spectral information using the TROPOMI BRDF product generated by the GRASP algorithm. Non-negative matrix factorization (NMF) is applied to extract spectral basis vectors from reference libraries and reconstruct key spectral features using limited bands. The method improves reflectance in challenging wavelengths, not only within 400–800 nm but also across the broader 400–2400 nm range, representing a cost-effective solution to narrow spectral gaps in multispectral data.
