Water monitoring with LifeLidar.

Fluorescence recorded after 405 nm laser excitation. The indices describe dissolved organic matter, chlorophyll-a and suspended particles; they are relative values, not concentrations.

Remote-sensing reflectance across 400–880 nm. The spectrum is used to classify optical water type and estimate water colour on the 21-step Forel-Ule scale.

Daily chlorophyll-a index with a 7-day median. Gaps indicate insufficient data; the vertical marker shows a sensor replacement.

Daily coloured dissolved organic matter (CDOM) index with a 7-day median. These are relative values, not concentrations.
