2018) Trophic state assessment of global inland waters using a MODIS-derived Forel-Ule index. Abstract 13 Eutrophication of inland waters is considered a serious global environmental 14 problem. Satellite remote sensing (RS) has been established as an important source of 15 information to determine the trophic state of inland waters through the retrieval of 16 optically active water quality parameters such as chlorophyll-a (Chl-a). However, the 17 use of RS techniques for assessment of the

In this study, we 20 developed a new RS approach to assess the trophic state of global inland water bodies 21 based on Moderate Resolution Imaging Spectroradiometer (MODIS) imagery and the 22 Forel-Ule index (FUI). First, the FUI was calculated from MODIS data by dividing 23 Africa, eastern Asia, and mid-northern and southeast North America. 38
