Assessing the Accuracy of PRISMA Standard Reflectance Products in Globally Distributed Aquatic Sites
PRISMA is the Italian Space Agency’s first proof-of-concept hyperspectral mission launched in March 2019. The present work aims to evaluate the accuracy of PRISMA’s standard Level 2d (L2d) products in visible and near-infrared (NIR) spectral regions over water bodies. For this assessment, an analyti...
