Proximal VIS-NIR Spectrometry to Retrieve Substance Concentrations in Surface Waters Using Partial Least Squares Modelling

Many water quality parameters such as concentrations of suspended matter, nutrients and algae directly or indirectly change the electromagnetic reflectance and transmission properties of surface water bodies. Optical measurement approaches have shown …

Lake Water Footprint Identification from Time-Series ICESat/GLAS Data

To provide high-quality data for time-series change detection of lake water level, an automatic and robust algorithm for lake water footprint (LWF) identification is developed. Based on the Ice, Cloud, and Land Elevation Satellite GLA14 data file, …
