Cover Story: Are physical atmospheric correction models most effective for water quality modeling or image-based models? To answer this long-standing debate, a comparative analysis was conducted to evaluate the limits of three image-based atmospheric correction models (top of the atmosphere (ToA), dark object subtraction (DOS), and cosine of solar zenith angle (COST)) and three physical models (atmospheric correction for flat terrain (ATCOR), fast line-of-sight atmospheric analysis of spectral hypercubes (FLAASH)), and ACOLITE) to retrieve inland suspended particulate matter concentrations using Landsat imagery. Contrary to expectations, image-based models outperformed physical models in terms of accuracy, particularly the DOS and COST models. View this paper
