Summary
A vertical profile of downwelling spectral irradiance at different depths within the water column was measured on the Deschutes River near Bend, OR, July 28, 2016, to support research on remote sensing of river discharge. 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 both the downwelling [...]
Summary
A vertical profile of downwelling spectral irradiance at different depths within the water column was measured on the Deschutes River near Bend, OR, July 28, 2016, to support research on remote sensing of river discharge. 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 both the downwelling irradiance spectra and the depths at which these measurements were made and can be used to characterize attenuation of light within the water column. This information can facilitate efforts to map river bathymetry from field spectra or passive optical remotely sensed data.

Purpose
This vertical profile of downwelling spectral was used to characterize the attenuation of light within the water column, which is an important control on the ability to infer water depth from passive optical image data or field spectra and constrains the maximum detectable depth. This kind of depth information could be incorporated into techniques for measuring river discharge from remotely sensed data.
