Abstract

ICESat-2’s Advanced Topographic Laser Altimeter System (ATLAS) has emerged as useful tool for calculating attenuation signals in natural surface waters, thus improving our understanding of particulates from open-ocean plankton to nearshore suspended terrigenous sediments. While several studies have employed methods based on Beer’s Law to derive attenuation coefficients (including through a machine-learning approach), a rigorous sensitivity test on specific tuning parameters and processing choices has not yet been performed. Here we present comprehensive sensitivity tests of solar background removal, noise removal, choice of bin sizes, surface...  more
