Field measurements of water column optical properties from the Kootenai River in northern Idaho, September 26-27, 2017, and similar data from several other rivers Field measurements of various optical properties of the water column were acquired from a single location on the Kootenai River in northern Idaho, September 26-27, 2017, to support research on remote sensing of rivers, particularly estimation of water depth from passive optical image data. The field measurements included in this data release include several parameters measured with three different instruments. A WetLabs EcoTriplet multi-probe was used to measure the volume scattering coefficient (Beta) at 700 nm, the back-scattering coefficient (b_b) at 700 nm, chlorophyll concentration, colored dissolved organic matter (CDOM) concentration, and turbidity. A Sequoia Scientific LISST-100X was used to measure the...

Downwelling spectral irradiance data were collected using an Analytical Spectral Devices FieldSpec3 spectroradiometer operated in irradiance mode and deployed from a customized measurement crane. The measurements were made near a boat launch downstream of Benham Falls. In addition, the depth at which each downwelling spectral irradiance measurement was made was obtained using an Onset Hobo pressure transducer mounted next to the spectroradiometer foreoptic on the crane. This data release provides...

Downwelling spectral irradiance data were collected using an Analytical Spectral Devices FieldSpec3 spectroradiometer operated in irradiance mode and deployed from a customized measurement crane. The measurements were made in a reach downstream of Jackson Lake referred to as Swallow bend. In addition, the depth at which each downwelling spectral irradiance measurement was made was obtained using an Onset Hobo pressure transducer mounted next to the spectroradiometer foreoptic on the crane....
