🧰 Description techniqueWater colour is can be used as an intuitive water quality attribute that can be measured by satellite sensors without knowledge of inherent optical properties. Colour is linked to clarity, concentration of phytoplankton, suspended matter and colored dissolved organic matter. | 📏 Accuracy / Resolution30-m pixel resolution allows for the observation of lakes down to about 1 ha size. | ||||
🗺 Case studyc. 45,000 observations over four years from 1486 lakes from a diverse range of optical water types in New Zealand (Lehmann et al., 2018). | |||||
