This data is related to a research project using sediment fingerprinting based on Diffuse Reflectance Infrared Fourier Transform Spectrometry (DRIFTS) to estimate sediment source contributions to suspended sediment in rivers<b>. </b>The research took place in the River Aire catchment, United Kingdom. The data was collected between 2014 and 2017.<div><br></div><div>Two types of data are available:<div><br><div><b>1. Suspended sediment concentrations during high-flow events</b> (SuspendedSedimentConcentration_RiverAire.csc). Samples were collected with a depth-integrating suspended sediment sampler from the side of the river at Brewery Wharf in the city center of Leeds (dates are indicated)</div><div><br></div><div><b>2. Diffuse Reflectance Infrared Fourier Transform Spectrometry (DRIFTS) spectra of sediment samples</b> </div><div>Type of samples: </div><div>- suspended sediment, </div><div>- bed sediment, </div><div>- sediment sources <b>(*)</b>,</div><div>- experimental mixtures of sediment source samples. </div><div>Each type of sample is included in a separate .CSV file<b> (**)</b></div><div><br></div><div><b>(*) </b>Sample IDs: CR, LR, MR (samples from eroding riverbanks in coals, limestone and millstone area respectively). CU, LU, MU (samples from uncultivated grassland soils in coals, limestone and millstone area respectively). U (urban street dust samples). Numbers 1-2-3 represent sub samples taken within one square meter.</div><div><br></div><div><b>(**)</b> First row of the columns in all DRIFTS files represent the wavelength (micrometer<sup>-1</sup>) ranging between 3799 and 651<br><div><br></div></div></div></div>
