Self‐diagnosis of model suitability for continuous measurements of stream‐dissolved organic carbon derived from in situ UV–visible spectroscopy

Dataset composed of continuous in-situ stream water measurements of water level, electric conductivity and optical parameters including UV-Vis beam attenuation coefficient (absorbance), spectral slopes from 275 to 295 nm and 350 to 400 nm, and their ratio. Matched to continuous data are discrete samples collected via autosampler or grab-collected where available for dissolved organic carbon concentration. PLS model results are also reported for training and continuous data.
