Many existing methods use heuristic rules to classify on a pixel-level regarding dust or dust-free. However, these heuristic rules are limited in applicability when the study area or the study period has changed. Based on a multisensor collocation dataset, we sought to utilize unsupervised machine learning techniques to detect and segment dust in multispectral satellite imagery. In this report, we describe the datasets used, discuss our methodology, and provide preliminary validation results.22 pagesen-USThis item is likely protected under Title 17 of the U.S. Copyright Law.
