Abstract
With the advent of Sentinel-2A new, unprecedented opportunities emerged for analyzing lakes by remote sensing with respect to spatial, radiometric, spectral and temporal resolution. This study is based on a Sentinel-2A scene acquired at Lake Starnberg, an oligotrophic, peri-alpine lake. Atmospheric correction with Sen2Cor worked well showing, however, a small overcorrection in some bands. The lake was analyzed with WASI-2D for suspended particulate matter (SPM) and absorption by coloured dissolved organic matter (aCDOM(440)) in optically deep water; in optically shallow, water bottom coverages and water depths were retrieved in addition. Compared to in situ measurements, SPM was overestimated whereas aCDOM(440) agreed well. Water depths estimation performed reasonably up to measured Secchi depth (RMSE: 0.42 m).
