Abstract
Remote retrieval of near-surface chlorophyll-a (Chla) concentration in small inland waters is challenging due to substantial in situ optical interferences of various water?constituents and uncertainties in the atmospheric correction process. Although various algorithms have been developed or adapted to estimate Chla from moderate-resolution terrestrial missions (~ 10 – 60 m), there remains a need for robust algorithms to retrieve Chla in small inland waters. Here, we train and test a support vector regression (SVR) model, which takes in satellite-derived remote-sensing reflectance spectra (
