Surface reflectance of remote sensing datasets contribute to various fields such as natural resources management (Liang et al., 2024), agricultural practices (Liu et al., 2020; Stratoulias et al., 2017), ecological monitoring (Liang et al., 2024), and climate studies (Liu et al., 2020), providing critical information about Earth's surface conditions and resources. Nonetheless, inaccuracies in the raw remote surface reflectance data, resulting from both internal sensor anomalies (Hu et al., 2012) and external atmospheric effects (Dash et al., 2011; Vermote et al., 2016), reveal that correction of these datasets is essential. Moreover, Surface Reflectance datasets of coastal and inland waters are significantly affected by cloud coverage (Wang & Chen, 2024) introducing noise (Qing et al., 2021) into the imagery and shadows. This study introduces a methodology to correct and fill in missing data from multispectral Level 2 Surface Reflectance daily time-series, by identifying logical errors and implementing Principal Component Analysis. The study successfully results in continuous two-decade surface reflectance dataset to assure its reliability and utility across various applications.
