Evaluating the Accuracy of Gaussian Approximations in VSWIR Imaging Spectroscopy Retrievals

The joint retrieval of surface reflectances and atmospheric parameters in visible/short-wave infrared (VSWIR) imaging spectroscopy is a computationally challenging high-dimensional problem. Using NASA's Surface Biology and Geology mission (SBG) as the motivational context, the uncertainty assoc...
