| Summary: | These date files provide observations, model calibration, and model testing results used in King and Neilson 2019, \"Quantifying Reach-Average Effects of Hyporheic Exchange on Arctic River Temperatures in an Area of Continuous Permafrost\" published in Water Resources Research. Note on Units: All temperature values are in degrees Celsius. All discharge values are in cubic meters per second All solute concentrations are in milligrams sodium-chloride per L Files Description: ParetoOptimal_Solute_Temperature.dat: Time series of simulated main channel solute breakthrough curve and temperature at 1500 m downstream of the injection location using the Pareto optimal model calibration.
